SUMMARY:[AP-S Seminar Series] Natalia K. Nikolova\, McMaster University\, Mar. 19\, 4pm EDT
DESCRIPTION:The University of Toronto Student Chapter of the IEEE Antennas and Propagation Society (AP-S) invites you to the following talk in our 2020-2021 seminar series: \nMicrowave and Millimeter-Wave Near-Field Imaging: Applications\, Methods\, and Challenges\, presented by Natalia K. Nikolova from McMaster University\, on Friday\, March 19\, 2021\, 4-5 pm EDT. \nAbstract: In the last decade\, we have witnessed dramatic decrease in the price and size of on-chip transceivers and radars along with their increased functionality. This has spurred unprecedented growth in imaging\, sensing and detection applications\, defining the current and future growth of wireless technology. \nWe will introduce the methods of real-time microwave and millimeter-wave imaging\, which allow to “see” inside optically opaque objects. The electromagnetic models of wave propagation that link the object’s electrical properties to the microwave measurements are briefly introduced with an emphasis on the approximations\, which enable real-time image reconstruction. We will discuss the detrimental effects of these approximations on the reconstructed images and how these effects are mitigated through the careful design of the acquisition apparatus and through data processing. We will briefly dive into the inner workings of two reconstruction methods\, microwave holography and the scattered-power mapping\, along with examples of real-time quantitative image reconstruction of complex dielectric objects. \nSpeaker: Natalia K. Nikolova of McMaster University \nBiography: \nNatalia K. Nikolova (IEEE S’93–M’97–SM’05–F’11) received the Dipl. Eng. (Radioelectronics) degree from the Technical University of Varna\, Bulgaria\, in 1989\, and the Ph.D. degree from the University of Electro-Communications\, Tokyo\, Japan\, in 1997. From 1998 to 1999\, she held a Postdoctoral Fellowship of the Natural Sciences and Engineering Research Council of Canada (NSERC) at Dalhousie University and McMaster University. In 1999\, she joined the Department of Electrical and Computer Engineering at McMaster University\, where she is currently a Professor.

SUMMARY:Glide symmetries: a new degree of freedom for the design of periodic structures
DESCRIPTION:On Monday\, February 8\, 2021 at 11:00 a.m.\, IEEE Antennas and Propagation Society is hosting “Glide Symmetries: A New Degree of Freedom for the Design of Periodic Structures”. \nDay & Time: Monday\, February 8\, 2021\n11:00 a.m. – 12:30 p.m. \nSpeaker: Oscar Quevedo-Teruel of KTH Royal Institute of Technology \nOrganizer(s): IEEE Antennas and Propagation Society \nLocation: Virtual – Zoom \nContact: George Eleftheriades \nAbstract: \nGlide symmetries were employed for electromagnetic purposes during the 60s and 70s. Those works were focused on one-dimensional structures with potential application in low-dispersive leaky wave antennas. However\, the development of planar/printed technologies in the 80s and 90s associated to their low-cost for low-frequency applications\, the studies of glide symmetries stopped. \nIn the beginning of the 21st century\, with arrival of metamaterials\, there was a significant development of the understanding of periodic structures\, and new methods of analysis were introduced. This theoretical development\, together with the interest of industry in mm-waves\, particularly for communications systems such as 5G\, created an opportunity to explore the possibilities of glide symmetries\, especially in two-dimensional configurations. \nGlide-symmetric structures has recently attracted the attention of researchers due to their attractive properties for practical applications. Among their interesting properties are low-dispersive responses in fully metallic structures such as parallel plate or co-planar waveguides (CPW)\, bandgaps associated to the symmetries and large electromagnetic bandgaps (EBGs). \nIn this talk\, Dr. Quevedo-Teruel will describe the most significant works in glide symmetries\, including their application for the design of gap-waveguide technology and planar lens antennas with steerable angles of radiation. \nRegister: Please visit https://events.vtools.ieee.org/m/256420 to register. \nBiography: \n\n\n\nOscar Quevedo-Teruel is a Senior Member of the IEEE. He received his Telecommunication Engineering Degree from Carlos III University of Madrid\, Spain in 2005\, part of which was done at Chalmers University of Technology in Gothenburg\, Sweden. He obtained his Ph.D. from Carlos III University of Madrid in 2010 and was then invited as a postdoctoral researcher to the University of Delft (The Netherlands).

SUMMARY:Microwaving a Biological Cell Alive ‒ Broadband Label-free Noninvasive Electrical Characterization of a Live Cell
DESCRIPTION:On Wednesday\, October 7\, 2020 at 4:00 p.m.\, Prof. James Hwang of Cornell University will present “Microwaving a Biological Cell Alive ‒ Broadband Label-free Noninvasive Electrical Characterization of a Live Cell”. \nDay & Time: Wednesday\, October 7\, 2020\n4:00 p.m. – 5:00 p.m. \nSpeaker: Prof. James Hwang of Cornell University \nOrganizer: IEEE Toronto Electromagnetics & Radiation Chapter \nLocation: Virtual – Zoom \nContact: George Eleftheriades \nAbstract: Microwave is not just for cooking\, smart cars\, or mobile phones. We can take advantage of the wide electromagnetic spectrum to do wonderful things that are more vital to our lives. For example\, microwave ablation of cancer tumor is already in wide use\, and microwave remote monitoring of vital signs is becoming more important as the population ages. \nThis talk will focus on a biomedical use of microwave at the single-cell level. At low power\, microwave can readily penetrate a cell membrane to interrogate what is inside a cell\, without cooking it or otherwise hurting it. It is currently the fastest\, most compact\, and least costly way to tell whether a cell is alive or dead. On the other hand\, at higher power but lower frequency\, the electromagnetic signal can interact strongly with the cell membrane to drill temporary holes of nanometer size. The nanopores allow drugs to diffuse into the cell and\, based on the reaction of the cell\, individualized medicine can be developed and drug development can be sped up in general. Conversely\, the nanopores allow strands of DNA molecules to be pulled out of the cell without killing it\, which can speed up genetic engineering. Lastly\, by changing both the power and frequency of the signal\, we can have either positive or negative dielectrophoresis effects\, which we have used to coerce a live cell to the examination table of Dr. Microwave\, then usher it out after examination. These interesting uses of microwave and the resulted fundamental knowledge about biological cells will be explored in the talk. \nRegister: Please visit https://events.vtools.ieee.org/m/239462 to register. \nBiography: James Hwang is Professor in the Department of Materials Science and Engineering at Cornell University. He graduated from the same department with a Ph.D. degree. After years of industrial experience at IBM\, Bell Labs\, GE\, and GAIN\, he spent most of his academic career at Lehigh University. He cofounded GAIN and QED; the latter became the public company IQE. Between 2011 and 2013\, he was the Program Officer for GHz-THz Electronics at the U.S. Air Force Office of Scientific Research. He has been a visiting professor at Cornell University in the US\, Marche Polytechnic University in Italy\, Nanyang Technological University in Singapore\, National Chiao Tung University in Taiwan\, Shanghai Jiao Tong University\, East China Normal University\, and University of Science and Technology in China.

SUMMARY:Automotive Radar – A Signal Processing Perspective on Current Technology and Future Systems
DESCRIPTION:Thursday March 5th\, 2020 at 4:00 p.m. Dr. Markus Gardill\, IEEE Distinguished Microwave Lecturer\, will be presenting an IEEE Distinguished Lecture “Automotive Radar – A Signal Processing Perspective on Current Technology and Future Systems”. \nDay & Time: Thursday March 5th\, 2020\n4:00 p.m. ‐ 5:00 p.m. \nSpeaker: Dr. Markus Gardill\nIEEE Distinguished Microwave Lecturer \nOrganizers: IEEE Toronto Electromagnetics & Radiation Chapter \nLocation: Bahen Centre\, Room BA 1180\nUniversity of Toronto – St. George Campus\n40 St George St\, Toronto\, ON M5S 2E4 \nContact: George V. Eleftheriades\, FRSC\, FIEEE \nAbstract: Radar systems are a key technology of modern vehicle safety & comfort systems. Without doubt it will only be the symbiosis of Radar\, Lidar and camera-based sensor systems which can enable advanced autonomous driving functions soon. Several next generation car models are such announced to have up to 10 radar sensors per vehicle\, allowing for the generation of a radar-based 360° surround view necessary for advanced driver assistance as well as semi-autonomous operation. Hence the demand from the automotive industry for high-precision\, multi-functional radar systems is higher than ever before\, and the increased requirements on functionality and sensor capabilities lead to research and development activities in the field of automotive radar systems in both industry and academic worlds. \nCurrent automotive radar technology is almost exclusively based on the principle of frequency-modulated continuous-wave (FMCW) radar\, which has been well known for several decades. However\, together with an increase of hardware capabilities such as higher carrier frequencies\, modulation bandwidths and ramp slopes\, as well as a scaling up of simultaneously utilized transmit and receive channels with independent modulation features\, new degrees of freedom have been added to traditional FMCW radar system design and signal processing. The anticipated presentation will accordingly introduce the topic with a review on the fundamentals of radar and FMCW radar. After introducing the system architecture of traditional and modern automotive FMCW radar sensors\, with e.g. insights into the concepts of distributed or centralized processing and sensor data fusion\, the presentation will dive into the details of fast-chirp FMCW processing – the modulation mode which is used by the vast majority of current automotive FMCW radar systems. Starting with the fundamentals of target range and velocity estimation based on the radar data matrix\, the spatial dimension available using modern single-input multiple-output (SIMO) and multiple-input multiple-output (MIMO) radar systems will be introduced and radar processing based on the radar data cube is discussed. Of interest is the topic of angular resolution – one of the key drawbacks which e.g. render Lidar systems superior to radar in some situations. Consequently\, traditional and modern methods for direction of arrival estimation in FMCW radar systems are presented\, starting from traditional monopulse-like algorithms to modern frameworks for superresolution DoA estimation. The presentation will then introduce the great challenge of FMCW radar system interference. While FMCW radar interference is a challenge which can be handled using adaptive signal processing in today’s systems\, it will become a severe problem with the increasing number of radar-sensors equipped vehicles in dense traffic situations in the near future and a solution to the expected increase in interference is still an open question. \nIt is this problem of interference\, together with some added functionality\, which motivated the proposal of alternative radar waveforms such as pseudo-random or orthogonal-frequency division multiplexing (OFDM) radar for automotive radar systems. Although not yet of great interest from an industrial perspective\, the fundamentals and capabilities of both technologies will be introduced in the remainder of the anticipated presentation. \nBiography:\nMarkus Gardill (S’11-M’15) was born in Bamberg\, Germany in 1985. \nHe received the Dipl.-Ing. and Dr.-Ing. degree in systems of information and multimedia technology/electrical engineering from the Friedrich-Alexander-University Erlangen-Nürnberg\, Germany\, in 2010 and 2015\, respectively. \nIn 2010\, he joined the Institute for Electronics Engineering at the Friedrich-Alexander-University Erlangen-Nürnberg as a research assistant and teaching fellow. \nFrom 2014 to 2015 he was head of the team Radio Communication Technology. \nIn late 2015 he joined the Robert Bosch GmbH as an R&D engineer for optical and imaging metrology systems and leading the cluster of non-destructive testing for the international production network.\nIn 2016 he joined the automotive radar business segment of InnoSenT GmbH\, where he is currently head of the group radar signal processing & tracking. \nHis main research interest include radar and communication systems\, antenna (array) design\, and signal processing algorithms. His particular interest is spatio-temporal processing such as e.g. beamforming and direction-of-arrival estimation with a focus on combining the worlds of signal processing and microwave/electromagnetics. \nDr. Gardill is an IEEE Young Professional. He is member of the IEEE Microwave Theory and Techniques Society (IEEE MTT-S) and currently serves as co-chair of the IEEE MTT-S Technical Committee Digital Signal Processing (MTT-9).\nHe regularly acts as reviewer and TPRC member for several journals and conferences\, will act as associate editor of the Transactions on Microwave Theory and Techniques beginning with 2020 and serves as Distinguished Microwave Lecturer (DML) for the DML term 2018-2020 with a presentation focussing automotive radar systems.

SUMMARY:Medical Applications of Microwaves
DESCRIPTION:Friday\, February 7\, 2020 Zoya Popovic\, Distinguished Professor and Lockheed Martin Endowed Chair of Electrical Engineering at the University of Colorado\, will be presenting “Medical Applications of Microwaves”. \nDay & Time: Friday\, February 7\, 2020\n3:00 p.m. ‐ 4:00 p.m. \nSpeakers: Zoya Popovic\nDistinguished Professor\nLockheed Martin Endowed Chair of Electrical Engineering\, University of Colorado \nOrganizers: IEEE Toronto Electromagnetics & Radiation Chapter \nLocation: Bahen Centre for Information Technology – Room 2135\n40 St George street\nToronto\, Ontario\nCanada M5S 2E4 \nRegister: https://meetings.vtools.ieee.org/m/219067 \nContact: Prof. Costas Sarris \nAbstract: This talk will first present a brief overview of the activities in the microwave group at the University of Colorado\, Boulder\, following a discussion on two topics that use microwave techniques for medical applications: (1) design of exciters and bore for human-sized 10.5-T MRI machines; and (2) a study of near-field radiometry for internal temperature measurements of the human body. The focus of the first topic is design of cavity and probes for improving uniformity of the circularly-polarized B-field inside phantoms for high-field travelling-wave MRI imagers. \nThe phenomenology of high-field imaging and its resulting challenges will be highlighted\, followed by simulation and experimental data using a research Siemens instrument. Although MRI can be used for measuring internal body temperature\, it is expensive\, large and slow. Radiometry is shown to be a feasible method for implementing a portable or even wearable microwave thermometer. \nOne of the possible frequencies of operation is the 1.4 GHz quiet band\, which is appropriate for centimeter penetration into tissues with minimized radio-frequency interference (RFI). The total blackbody power from a tissue stack is received by a probe placed on the skin\, designed to receive a high percentage of the total power from a buried tissue layer. Temperature retrieval for sub-surface tissue layers is performed using near-field weighting functions\, obtained by full-wave simulations with known tissue complex electrical parameters. \nMeasurements are presented using a calibrated Dicke radiometer at 1.4GHz for various phantom tissues. It is shown that temperature can be tracked within a fraction of a degree for a phantom muscle tissue layer under phantom fat and skin layers. \nBiography: Zoya Popovic is a Distinguished Professor and the Lockheed Martin Endowed Chair of Electrical Engineering at the University of Colorado. She obtained her Dipl.Ing. degree at the University of Belgrade\, Serbia\, and her Ph.D. at Caltech. In 2001/03 and 2014\, she was a Visiting Professor with the Technical University of Munich\, Germany and ISAE in Toulouse\, France\, respectively. She was a Chair of Excellence at Carlos III University in Madrid in 2018-19. She has graduated 60 PhDs and currently advises 14 doctoral students in various areas of microwave engineering. She is a Fellow of the IEEE and the recipient of two IEEE MTT Microwave Prizes for best journal papers\, the White House NSF Presidential Faculty Fellow award\, the URSI Issac Koga Gold Medal\, the ASEE/HP Terman Medal and the German Humboldt Research Award. She was named IEEE MTT Distinguished Educator in 2013 and the University of Colorado Distinguished Research Lecturer in 2015. She has a husband physicist and three daughters who can all solder.

However\, together with an increase of hardware capabilities such as higher carrier frequencies\, modulation bandwidths and ramp slopes\, as well as a scaling up of simultaneously utilized transmit and receive channels with independent modulation features\, new degrees of freedom have been added to traditional FMCW radar system design and signal processing. The anticipated presentation will accordingly introduce the topic with a review on the fundamentals of radar and FMCW radar. After introducing the system architecture of traditional and modern automotive FMCW radar sensors\, with e.g. insights into the concepts of distributed or centralized processing and sensor data fusion\, the presentation will dive into the details of fast-chirp FMCW processing – the modulation mode which is used by the vast majority of current automotive FMCW radar systems. Starting with the fundamentals of target range and velocity estimation based on the radar data matrix\, the spatial dimension available using modern single-input multiple-output (SIMO) and multiple-input multiple-output (MIMO) radar systems will be introduced and radar processing based on the radar data cube is discussed. Of interest is the topic of angular resolution – one of the key drawbacks which e.g. render Lidar systems superior to radar in some situations. Consequently\, traditional and modern methods for direction of arrival estimation in FMCW radar systems are presented\, starting from traditional monopulse-like algorithms to modern frameworks for superresolution DoA estimation. The presentation will then introduce the great challenge of FMCW radar system interference. While FMCW radar interference is a challenge which can be handled using adaptive signal processing in today’s systems\, it will become a severe problem with the increasing number of radar-sensors equipped vehicles in dense traffic situations in the near future and a solution to the expected increase in interference is still an open question. \nIt is this problem of interference\, together with some added functionality\, which motivated the proposal of alternative radar waveforms such as pseudo-random or orthogonal-frequency division multiplexing (OFDM) radar for automotive radar systems. Although not yet of great interest from an industrial perspective\, the fundamentals and capabilities of both technologies will be introduced in the remainder of the anticipated presentation. \nBiography:\nMarkus Gardill (S’11-M’15) was born in Bamberg\, Germany in 1985. \nHe received the Dipl.-Ing. and Dr.-Ing. degree in systems of information and multimedia technology/electrical engineering from the Friedrich-Alexander-University Erlangen-Nürnberg\, Germany\, in 2010 and 2015\, respectively. \nIn 2010\, he joined the Institute for Electronics Engineering at the Friedrich-Alexander-University Erlangen-Nürnberg as a research assistant and teaching fellow. \nFrom 2014 to 2015 he was head of the team Radio Communication Technology. \nIn late 2015 he joined the Robert Bosch GmbH as an R&D engineer for optical and imaging metrology systems and leading the cluster of non-destructive testing for the international production network.\nIn 2016 he joined the automotive radar business segment of InnoSenT GmbH\, where he is currently head of the group radar signal processing & tracking. \nHis main research interest include radar and communication systems\, antenna (array) design\, and signal processing algorithms.

SUMMARY:Analog Photonic Systems: Features & Techniques to Optimize Performance
DESCRIPTION:Monday October 7th\, 2019 at 4:30 p.m. Dr. Edward Ackerman\, Vice President of R&D for Photonic Systems and IEEE Fellow\, will be presenting “Analog Photonic Systems: Features & Techniques to Optimize Performance”. \nDay & Time: Monday October 7th\, 2019\n4:30 p.m. ‐ 5:30 p.m. \nSpeaker: Dr. Edward Ackerman\nVice President of R&D for Photonic Systems\, Inc. of Billerica\, Massachusetts\nIEEE Fellow \nOrganizers: IEEE Toronto Electromagnetics & Radiation Chapter \nLocation: Sidney Smith Hall – Room SS 2108\nUniversity of Toronto – St. George Campus\n100 St George St\, Toronto\, ON M5S 3G3 \nContact: George V. Eleftheriades\, FRSC\, FIEEE \nAbstract: Both the scientific and the defense communities wish to receive and process information occupying ever-wider portions of the electromagnetic spectrum. This can often create an analog-to-digital conversion “bottleneck”. Analog photonic channelization\, linearization\, and frequency conversion systems can be designed to alleviate this bottleneck. Moreover\, the low loss and dispersion of optical fiber and integrated optical waveguides enable most of the components in a broadband sensing or communication system\, including all of the analog-to-digital and digital processing hardware\, to be situated many feet or even miles from the antennas or other sensors with almost no performance penalty. The anticipated presentation will highlight the advantages and other features of analog photonic systems (including some specific systems that the author has constructed and tested for the US Department of Defense)\, and will review and explain multiple techniques for optimizing their performance. \nBiography:\nEdward Ackerman received Ph.D. degree in electrical engineering from Drexel University in 1994. From 1989 through 1994 he was employed as a microwave photonics engineer at Martin Marietta’s Electronics Laboratory in Syracuse\, New York. From 1995 to July 1999 he was a member of the Technical Staff at MIT Lincoln Laboratory. Since 1999 he has been Vice President of R&D for Photonic Systems\, Inc. of Billerica\, Massachusetts. Dr. Ackerman is a Fellow of the IEEE.

SUMMARY:Differential Microstrip Antennas
DESCRIPTION:Thursday\, August 23rd 2018\, Prof. Yueping Zhang at Nanyang Technological University\, Singapore\, is presenting an Electromagnetics and Radiation IEEE Distinguished Lecture “Differential Microstrip Antennas”. \nDay & Time: Thursday August 23rd\, 2018\n3:00 p.m. ‐ 4:00 p.m. \nSpeaker: Prof. Yueping Zhang at Nanyang Technological University\, Singapore \nOrganizers: IEEE Toronto Electromagnetics & Radiation Chapter \nLocation: Bahen Center of Information Technology\, Room BA1230\n40 St George Street\nToronto\, Ontario\nCanada M5S 2E4 \nContact: Costas Sarris \nAbstract: The earliest antennas implemented by Hertz for the discovery of radio waves were dipole and loop. They are differential. It was Marconi who introduced the ground concept into antennas and realized single-ended monopole antennas for wireless transmission. Compared with differential antennas\, single-ended antennas have smaller size and therefore single-ended antennas have dominated in antenna designs. Compared with single-ended circuits\, differential circuits permit higher linearity and lower offset and make them immune to power supply variations\, temperature changes\, and substrate noise. As a result\, differential circuits have dominated in integrated circuit designs. Differential circuits call for differential antennas. This is particularly essential in highly-integrated system-on-chip and system-in-package solutions where the system ground plane may be much smaller than one free-space wavelength. Differential antennas perfectly marry (match) with differential circuits. No lossy balanced/unbalanced conversion circuit is needed. As a result\, the receiver noise performance and transmitter power efficiency are improved. \nIn this lecture\, I present differential microstrip antennas with an emphasis on the comparison of them with single-ended counterparts. First\, I extend the well-known cavity model for the single-ended microstrip antennas to analyze the input impedance and radiation characteristics of differential microstrip antennas. Then I examine the design formulas to determine the patch dimensions and the location of the feed point for single-ended microstrip antennas to design differential microstrip antennas. It is shown that the patch length can still be designed using the formulas for the required resonant frequency but the patch width calculated by the formula usually needs to be widen to ensure the excitation of the fundamental mode using the probe feeds. The condition that links the patch width\, the locations of the probe feeds\, and the excitation of the fundamental mode is the electrical separation\, which is a new and unique concept specifically conceived for the design of differential microstrip antennas. Next\, I turn to the miniaturization of differential microstrip antennas and discuss some latest achievements. Finally\, I summarize the lecture and provide recommendations. \nBiography: ZHANG Yueping is a full Professor of Electronic Engineering with the School of Electrical and Electronic Engineering at Nanyang Technological University\, Singapore\, a Distinguished Lecturer of the IEEE Antennas and Propagation Society (IEEE AP-S)\, and a Fellow of IEEE. \nProf. Zhang was a Member of the Field Award Committee of the IEEE AP-S (2015-2017)\, an Associate Editor of the IEEE Transactions on Antennas and Propagation (2010-2016)\, and the Chair of the IEEE Singapore MTT/AP joint Chapter (2012).

SUMMARY:Imaging Tissue and Treating Cancer with Microwaves
DESCRIPTION:Thursday January 28\, 2016 at 3:00 p.m. Professor Susan Hagness\, University of Wisconsin-Madison\, will be presenting “Imaging Tissue and Treating Cancer with Microwaves”. \nSpeaker: Professor Susan Hagness\nUniversity of Wisconsin-Madison \nDay & Time: Thursday\, January 28\, 2016\n3:00 p.m. \nLocation: Sandford Fleming Building\, 10 King’s College Rd\nRoom SF1105 \nOrganizer: IEEE Toronto Electromagnetics and Radiation Chapter \nContact: Costas D. Sarris \nAbstract: The endogenous (and possibly exogenously influenced) dielectric properties of tissue at microwave frequencies vary across different tissue types and physiological states. These properties may be exploited to differentiate tissues via low-power microwave imaging and to selectively heat diseased tissue at higher power levels. This presentation will highlight recent theoretical and experimental advances in low-cost microwave theranostics – that is\, diagnostic and therapeutic microwave-based technologies – with an emphasis on breast imaging and targeted cancer treatment. On the diagnostic side\, 3-D quantitative microwave imaging technology has the potential to address several important clinical needs in breast imaging\, including evaluating breast density as part of a patient’s individualized risk assessment\, screening women who are at higher risk for cancer\, and monitoring changes in breast tissue in response to prevention and treatment protocols. On the therapeutic side\, minimally invasive microwave ablation using miniaturized antennas as interstitial heating probes is emerging as a less invasive alternative to surgical resection and more effective and versatile alternative to conventional thermoablative techniques for the treatment of primary tumors. \nBiography: Susan C. Hagness received the B.S. degree with highest honors and the Ph.D. degree in electrical engineering from Northwestern University in 1993 and 1998\, respectively.

SUMMARY:The Wonderful World of Nonlinearity: Modeling and Characterization of RF and Microwave Circuits
DESCRIPTION:Monday January 18\, 2016 at 5:00 p.m. Jose C. Pedro\, Professor at the University of Aveiro\, will be presenting a Distinguished Microwave Lecture\, on “The Wonderful World of Nonlinearity: Modeling and Characterization of RF and Microwave Circuits”. \nSpeaker: Jose C. Pedro\nUniversity of Aveiro \nDay & Time: Monday\, January 18\, 2016\n5:00 p.m. – 6:00 p.m. \nLocation: Room GB405\, Galbraith Building\n35 St. George Street\, Toronto\, M5S 1A4 \nOrganizer: IEEE Toronto Electromagnetics and Radiation Chapter \nContact: George V. Eleftheriades \nAbstract: Despite the many studies that have been undertaken to understand the wonderful world of nonlinearity\, most undergraduate electrical engineering programs are still confined to linear analysis and design tools. As a result\, the vast majority of microwave designers still cannot profit from the significant technological advancements that have been made in nonlinear circuit simulation\, active device modeling and new instrumentation for performance verification. So\, they tend to conduct their designs relying on experience\, empirical concepts\, and many trial and error iterations in the lab.\nThis talk will reveal the ubiquitous presence of nonlinearity in all RF and microwave circuits and the recent efforts made to understand\, model\, predict\, and measure its diverse manifestations. We aim to bring microwave engineers’ attention to newly available techniques\, and attract researchers to pursue further studies on this scientifically exciting topic.\nStarting with some elementary properties of nonlinear circuits (like nonlinear signal distortion\, harmonic generation\, frequency conversion and spectral regrowth)\, we will show that nonlinearity is present in all wireless circuits\, either to perform a desired signal operation or as unintentional distortion. In this way\, we will show how oscillators\, modulators or mixers could not exist without nonlinearity\, while power-amplifier designers struggle to get rid of its distortion effects.\nAfter this theoretical overview\, we will introduce some recent advancements in nonlinear microwave circuit analysis tools and illustrate different types of models that are currently being used to represent and predict device\, circuit\, and system performance. Finally\, we will focus the talk on the key metrics that are used to characterize nonlinear behavior\, as well as newly developed lab instruments and their ability to assess device performance. \nBiography: José C. Pedro received the diploma\, doctoral and habilitation degrees in electronics and telecommunications engineering\, from University of Aveiro\, Portugal\, in 1985\, 1993 and 2002\, respectively.\nFrom 1985 to 1993 he was an Assistant Lecturer at University of Aveiro\, and a Professor since 1993. Currently he is a Full Professor at the same University\, and a Senior Research Scientist at the Institute of Telecommunications.\nHis main scientific interests include active device modeling and the analysis and design of various nonlinear microwave circuits\, in particular\, the design of highly linear multi-carrier power amplifiers and mixers.

SUMMARY:Applications of Miniaturized-Element Frequency Selective Surfaces in Designing Microwave Lenses\, Reflectarrays\, and Polarization Converters
DESCRIPTION:Friday December 11\, 2015 at 4:00 p.m. Prof. Nader Behdad of University of Wisconsin – Madison\, will be presenting “Applications of Miniaturized-Element Frequency Selective Surfaces in Designing Microwave Lenses\, Reflectarrays\, and Polarization Converters”. \nSpeaker: Prof. Nader Behdad\nUniversity of Wisconsin – Madison \nDay & Time: Friday\, December 11\, 2015\n4:00 p.m. \nLocation: Room BA1210\, Bahen Center for Information Technology\n40 St. George Street\, Toronto\, ON\, M5S 2E4 \nOrganizer: IEEE Toronto Electromagnetics and Radiation Chapter \nContact: Sean Victor Hum \nAbstract: Over the past several years\, we have conducted research on a class of frequency selective surfaces with building blocks that consist of cascaded arrays of non-resonant\, sub-wavelength periodic structures. Due to the small lateral dimensions and thicknesses of their unit cells\, these structures are referred to as miniaturized-element frequency selective surfaces (MEFSSs). As spatial filters\, MEFSSs can be designed to provide a wide range of response types with arbitrary levels of selectivity. MEFSSs capable of operating at extremely high incident power levels have also been developed and experimentally demonstrated for operation as spatial filters in HPM systems. Finally\, MEFSSs having suppressed harmonics over extremely broad bandwidths have been developed for reduction of radar signatures of antennas and other objects. \nIn addition to acting as spatial filters\, the building blocks of MEFSSs can be used to serve other purposes as well. For example\, by using the unit cells of a band-pass or a low-pass MEFSS as a spatial phase shifter or a spatial time-delay unit (TDU)\, wideband\, true-time-delay lenses and reflectarrays may be designed. By using anisotropic versions of these spatial TDUs\, wideband linear-to-circular polarization converters or polarization selective surfaces can be designed. In this presentation\, I will first briefly discuss the principles of operation of MEFSSs and present examples of spatial filters developed for different applications. Subsequently\, I will discuss three specific applications where the unit cells of MEFSSs are used as transmissive or reflective time-delay units. These include the development of wideband true-time-delay microwave lenses and reflectarrays as well as broadband linear-to-circular polarization converters designed using anisotropic time delay units. \nBiography: Nader Behdad received the B.S. degree in Electrical Engineering from Sharif University of Technology (Tehran\, Iran) in 2000 and the M.S. and Ph.D. degrees in Electrical Engineering from University of Michigan (Ann Arbor\, MI\, U.S.A.) in 2003 and 2006 respectively.

SUMMARY:Novel Single-Source Integral Equation for Solution of Electromagnetic Scattering Problems on Penetrable Objects
DESCRIPTION:Tuesday November 17\, 2015 at 4:00 p.m. Vladimir Okhmatovski\, Associate Professor in the Department of Electrical and Computer Engineering at the University of Manitoba\, will be presenting “Novel Single-Source Integral Equation for Solution of Electromagnetic Scattering Problems on Penetrable Objects”. \nSpeaker: Vladimir Okhmatovski\nAssociate Professor\nDepartment of Electrical and Computer Engineering at the University of Manitoba \nDay & Time: Tuesday\, November 17\, 2015\n4:00 p.m. \nLocation: Room BA1210\nBahen Center for Information Technology\n40 St. George Street\, Toronto\nM5S2E4 \nOrganizer: IEEE Toronto Electromagnetics & Radiation Chapter \nContact: Costas D. Sarris\, Email:costas.sarris@utoronto.ca \nAbstract: A new Surface–Volume–Surface Electric Field Integral Equation (SVS-EFIE) is discussed. The SVS-EFIE is derived from the volume integral equation by representing the electric field inside the scatterer as a superposition of the waves emanating from its cross section’s boundary. The SVS-EFIE has several advantages. While being rigorous in nature\, it features half of the degrees of freedom compared to the traditional surface integral equation formulations such as PMCHWT and it requires only electric-field-type of Green’s function instead ofboth electric and magnetic field types. The latter property brings significant simplifications to solution of the scattering problems on the objects situated in multilayered media. \nBoth scalar and vector formulations of the SVS-EFIE equation has been developed for solution of 2D scattering problems on penetrable cylinders under TM and TE polarizations. The SVS-EFIE has been also been applied to the solution of the quasi-magneetostatic problems of current flow in complex interconnects in both homogeneous and multilayered media. Detailed description of the method of moment discretization and resultant matrices is discussed. Due to the presence of a product of surface-to-volume and volume-to-surface integral operators\, the discretization of the novel SVS-EFIE requires both surface and volume meshes. In order to validate the presented technique\, the numericalresults are compared with the reference solutions. \nBiography: Vladimir Okhmatovski received Ph.D. degree in antennas and microwave circuits from the Moscow Power Engineering Institute\, Moscow\, Russia in 1997. He was a Post-Doctoral Research Associate with the National Technical University of Athens from 1998 to 1999 and with the University of Illinois at Urbana-Champaign from 1999 to 2003. From 2003 to 2004\, he was with the Department of Custom Integrated Circuits at Cadence Design Systems in Tempe\, Arizona. In 2004\, he joined the Department of Electrical and Computer Engineering\, University of Manitoba\, where is currently an Associate Professor. His research interests are the fast algorithms of electromagnetics\, high-performance computing\, modeling of interconnects\, and inverse problems.

SUMMARY:Parallel-MLFMA Solutions of Large-Scale Problems Involving Dielectric and Composite Metamaterial Structures
DESCRIPTION:July 15\, 2015 at 4:00 p.m. Prof. Levent Gurel will be presenting “Parallel-MLFMA Solutions of Large-Scale Problems Involving Dielectric and Composite Metamaterial Structures”. [Distinguished Lecture] \nSpeaker: Prof. Levent Gürel\nCEO\, ABAKUS Computing Technologies Adjunct Professor\, Dept. of ECE\, University of Illinois at Urbana-Champaign \nDay & Time: Wednesday\, July 15\, 2015\n4:00 p.m. – 5:00 p.m. \nLocation: Room BA 1210\nBahen Centre\nUniversity of Toronto – St. George Campus\n40 St. George Street \nClick here to see the Map \nOrganizer: IEEE Electromagnetics & Radiation Joint Chapter \nAbstract: It is possible to solve extremely large electromagnetics problems accurately and efficiently by using the multilevel fast multipole algorithm (MLFMA) and parallel MLFMA. This has important implications in terms of obtaining the solution of previously intractable physical\, real-life\, and scientific problems in various areas\, such as (subsurface) scattering\, optics\, bioelectromagnetics\, metamaterials\, nanotechnology\, remote sensing\, etc. Accurate simulations of such real-life electromagnetics problems with integral equations require the solution of dense matrix equations involving millions of unknowns. Most recently\, we have achieved the solutions of larger than 1\,000\,000\,000×1\,000\,000\,000 (one billion!) dense matrix equations! Solutions of these extremely large problems cannot be achieved easily\, even when using the most powerful computers with state-of-the-art technology. Instead\, we have been solving some of the world’s largest integral-equation problems in computational electromagnetics by employing fast algorithms implemented on parallel computers. For more information: www.abakus.computing.technology \nIn this talk\, following a general introduction to our work in computational electromagnetics\, I will present integral-equation and MLFMA formulations of dielectric/composite structures. Then\, I will continue with rigorous modeling of three-dimensional optical metamaterial and plasmonic structures that are composed of multiple coexisting dielectric and/or conducting parts. Such composite structures may possess diverse values of conductivities and dielectric constants\, including negative permittivity and permeability. It is possible to formulate and use different types of integral equations depending on which ones have better conditioning properties. I will briefly mention the development of effective Schur-complement preconditioners specifically for dielectric problems. Solutions of complicated real-life problems involving metamaterial structures\, red blood cells\, and dielectric photonic crystals will be presented. If time permits\, various challenges encountered during the solutions may be touched upon. \nBiography: Prof. Levent Gürel (Fellow of IEEE\, ACES\, and EMA) received the M.S. and Ph.D. degrees from the University of Illinois at Urbana-Champaign (UIUC) in 1988 and 1991\, respectively\, in electrical and computer engineering.
