    Room BA1210, Bahen Centre for Information Technology, University of Toronto

    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”. Speaker: Vladimir Okhmatovski Associate Professor Department of Electrical and Computer Engineering at the University of Manitoba Day & Time: Tuesday, November 17, 2015 4:00 p.m. Location: Room BA1210 Bahen Center for Information Technology 40 St. George Street, Toronto M5S2E4 Organizer: IEEE Toronto Electromagnetics & Radiation Chapter Contact: Costas D. Sarris, Email:costas.sarris@utoronto.ca Abstract: 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. Both 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.

Speaker: Mohammad Norouzi PhD Candidate Day & Time: Thursday, November 19, 2015 1:00 p.m. – 2:00 p.m. Location: Room ENG 106 George Vari Engineering and Computing Centre Ryerson University 245 Church Street Toronto Organizer: IEEE Toronto Computer, Magnetics and Instrument-Measurement Chapters Contact: Maryam Davoudpour, Email:maryam.davoudpour@ieee.org Abstract: Scalable similarity search on images, documents, and user activities benefits generic search, data visualization, and recommendation systems. This talk concerns the design of algorithms and machine learning tools for faster and more accurate similarity search. The proposed techniques advocate the use of discrete codes for representing the similarity structure of data in a compact way. In particular, I will discuss how one can learn to map high-dimensional data onto binary codes with a metric learning approach. Then, I will describe a simple algorithm for fast exact nearest neighbour search in Hamming distance, which exhibits sub-linear query time performance. Going beyond binary codes, I will highlight a compositional generalization of k-means clustering which maps data points onto integer codes with storage and search costs that grow sub-linearly in the number of cluster centers. This representation improves upon binary codes, and provides an even more precise approximation of Euclidean distance. Experimental results are reported on multiple datasets including a dataset of SIFT descriptors with 1B entries. Biography: Mohammad Norouzi is a PhD candidate in computer science at the University of Toronto. His research lies at the intersection of machine learning and computer vision. He is a recipient of a Google US/Canada PhD fellowship in machine learning. He is going to join Google as a research scientist in January 2016.

Cars that can park themselves, provide lane-departure warning, and monitor the driver alertness are marketed with affordable prices. The sensing and processing power of cars are increasing, enabling various safety-enhancing features, such as blind-spot warning, adaptive headlights, adaptive cruise control, and so on. In this talk, we will discuss the next steps for autonomous vehicles. In particular, we will project the path forward by transitioning from autonomous cars to cognitive and intelligent vehicles. Future cars will be enabled with car-to-car and car-to-infrastructure communication capabilities. We will review such enhancement and will focus on two recent research directives that will make future cars intelligent. The two enablers are compressive sensing and network coding. We will show that cooperative compressive sensing can reduce the wireless channel congestion, which is the main challenge in dense vehicular networks. To discuss the communications aspects of vehicular networks, we will introduce a repetition-based medium access control method using positive orthogonal codes, and then propose an opportunistic network-coding scheme to enhance the reliability of communication. We will finally discuss some open research issues. Biography: Shahrokh Valaee is with the Edward S.

  • Applications of Miniaturized-Element Frequency Selective Surfaces in Designing Microwave Lenses, Reflectarrays, and Polarization Converters

    Room BA1210, Bahen Center for Information Technology, 40 St. George Street, Toronto

    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”. Speaker: Prof. Nader Behdad University of Wisconsin – Madison Day & Time: Friday, December 11, 2015 4:00 p.m. Location: Room BA1210, Bahen Center for Information Technology 40 St. George Street, Toronto, ON, M5S 2E4 Organizer: IEEE Toronto Electromagnetics and Radiation Chapter Contact: Sean Victor Hum Abstract: 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. In 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.

  • The Wonderful World of Nonlinearity: Modeling and Characterization of RF and Microwave Circuits

    Room GB405, Galbraith Building, 35 St. George Street, Toronto, M5S 1A4

    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”. Speaker: Jose C. Pedro University of Aveiro Day & Time: Monday, January 18, 2016 5:00 p.m. – 6:00 p.m. Location: Room GB405, Galbraith Building 35 St. George Street, Toronto, M5S 1A4 Organizer: IEEE Toronto Electromagnetics and Radiation Chapter Contact: George V. Eleftheriades Abstract: 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. This 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. Starting 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. After 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.

  • Linearization Techniques for Push-Pull Amplifiers

    University of Toronto, Bahen Centre, Room BA1230

    Thursday January 28, 2016 at 11:10 a.m. Dr. Rinaldo Castello, IEEE Fellow, will be presenting “Linearization Techniques for Push-Pull Amplifiers”. Speaker: Dr. Rinaldo Castello IEEE Fellow University of Pavia, Italy Day & Time: Thursday, January 28, 2016 11:10 a.m. Location: University of Toronto, Bahen Centre, Room BA1230 Organizer: Solid-State Circuits Society Contact: Dustin Dunwell Abstract: Amplifiers that need to drive heavy loads (low resistances and/or large capacitances) or to handle high current signals with good efficiency generally use a push-pull output stage. This intrinsically creates large open-loop distortion components that need to be compressed through feedback to insure high closed-loop linearity. Minimizing close loop residual distortion involves three steps that will be discussed. First, eliminate all open-loop source of distortion not intrinsic to the proper operation of the push pull structure. Second, choose the amplifier topology that gives the maximum close loop compression of the open-loop distortion components for a given bandwidth. Third, maximize the open-loop gain in the signal band and/or the unity gain bandwidth of the amplifier for a given topology while insuring stability in the presence of variable loads. Biography: Rinaldo Castello (S’78–M’78–SM’92–F’99) graduated from the University of Genova (summa cum laude) in 1977 and received the M.S. and the Ph.

  • Imaging Tissue and Treating Cancer with Microwaves

    Sandford Fleming Building, 10 King’s College Rd Room, SF1105

    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”. Speaker: Professor Susan Hagness University of Wisconsin-Madison Day & Time: Thursday, January 28, 2016 3:00 p.m. Location: Sandford Fleming Building, 10 King’s College Rd Room SF1105 Organizer: IEEE Toronto Electromagnetics and Radiation Chapter Contact: Costas D. Sarris Abstract: 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.
