Microwave photonics (MWP) is a typical optical signal processing application for optical communications, antenna systems, and 5G/6G networks. At the same time, optical frequency combs (OFC) and programmable optical filters enable this system to be reconfigurable. There are several approaches to creating OFC lines, such as the micro-ring resonator, cascaded electro-optic modulator, and mode-locked laser (MLL), in which the quantum dash (QDash) MLL is an ideal on-chip OFC source to provide low relative intensity noise (RIN), narrow linewidth, and flat comb spectrum. In this seminar, we will present three typical applications of MWP systems using QDash MLL as the OFC source. The photonic beamforming illustrates a phased antenna array system that can do directional radiation and scanning. The MWP filter is a reconfigurable finite impulse response (FIR) filter, and a specially designed MWP filter can also be used for instantaneous frequency measurement. In partnership with the (https://nrc.canada.ca/en/research-development/research-collaboration/programs/high-throughput-secure-networks-challenge-program)Challenge program at National Research Council (NRC), we invite you to join this virtual seminar series to promote scientific information sharing, discussions, and interactions between researchers.

Magnetic Hardening in Low-Dimensional Ferromagnets By: Dr. J. Ping Liu Department of Physics, University of Texas at Arlington, Arlington, TX, USA IEEE Magnetics Society Distinguished Lecturer 2023 How “hard” (coercive) a ferromagnet can be has been a puzzle for a century. Seven decades ago, William Fuller Brown offered his famous theorem to correlate coercivity with the magnetocrystalline anisotropy fields in ferromagnetic materials. However, the experimental coercivity values have been far below the calculated levels given by the theorem, which is called Brown’s coercivity paradox. Researchers have attempted to solve the paradox with sustained efforts; however, the paradox remains unsolved, and coercivity still cannot be predicted and calculated quantitatively by modeling. Progress has been made in the past 20 years in understanding coercivity mechanisms in nanoscale low- dimensional ferromagnets. In fact, ferromagnetism is a size-dependent physical phenomenon, as revealed by theoretical studies. However, nanoscale ferromagnetic samples with controllable size and shape have been available only in recent times. By adopting newly developed salt-matrix annealing, surfactant-assisted milling, and improved hydrothermal and chemical solution techniques, we used a bottom-up approach to produce nanostructured magnets and have successfully synthesized monodisperse ferromagnetic Fe–Pt, Fe–Co, and Sm–Co nanoparticles and Co nanowires with extraordinary properties, which are strongly size- and shape-dependent. A study on size-dependent Curie temperature of the L10 ferromagnetic nanoparticles with sizes down to 2 nm has experimentally proved a finite-size effect. A systematic study of nanowires with extremely high coercivity above their magnetocrystalline anisotropy fields has opened a door to the solution of Brown’s paradox. Speaker(s): Dr. J.

As the popularity of solar panels increases, significant research is being performed to mitigate the power losses due to partial shading in photovoltaic power plants. One way to reduce the effects of partial shading conditions is by using bypass–diodes. In order to accurately model the PV cell with bypass diodes, it is necessary to consider both series and parallel configurations of bypass–diodes, as well as the thermal behavior of bypass–diodes. This research constructs an electro–thermal modular model for any size photovoltaic system and includes the effects of both the photovoltaic cells and bypass–diodes. Speaker(s): Dr. Hector R.

Join the IEEE Toronto Instrumentation & Measurement – Robotics & Automation Joint Chapter for a technical talk on the Wearable Mechatronic Garments for Motion Assessment and Support presented by Dr. Ana Luisa Trejos. Wednesday, August 9, 2023 @ 4:00 – 5:00 PM Abstract: More than 3.5 billion people suffer from neurological or musculoskeletal disorders. The aging population and growing obesity rates in Canada are predicted to substantially increase the prevalence of these conditions, which result in limited mobility and a reduced quality of life. The rehabilitation programs required to recover from these conditions are expensive, time consuming, overwhelming, and limited in their effectiveness. Incomplete recovery results in chronic pain and disability associated with limited mobility that costs Canadians over $20 billion each year in direct and indirect costs. To help patients recover fully from mobility-related disorders or to assist with long-lasting mobility issues, Dr. Trejos is leading an interdisciplinary research team focused on the design and development of wearable biomechatronic devices. The ultimate goal for these advanced technologies is to have them monitor patient performance and actively respond to their needs in real time by providing therapy, ensuring adherence and engagement, and directly communicating with clinicians. This talk will focus on presenting our progress to date at the Wearable Biomechatronics Laboratory, focusing on the design of novel unobtrusive actuators, embedded sensors for tracking patient biosignals, control systems that advance the intelligence of the devices, and user interfaces to communicate with patients and clinicians.

Join the IEEE Toronto Instrumentation & Measurement – Robotics & Automation Joint Chapter for a talk on the Diagnostic and Prognostic Medical Devices, presented by Dr. Razieh (Neda) Salahandish. Wednesday, August 16, 2023 @ 4:00 – 5:00 PM Abstract: Clinicians are increasingly interested in employing innovative engineering tools and techniques for early-stage disease diagnosis, including infectious diseases, cancers, and brain injury disorders, to reduce economic, social, and health burdens. Integrated biosensing systems, which combine various scientific disciplines such as biology, chemistry, medicine, electrical engineering, and mechanical engineering, are viewed as effective approaches to tackle the associated medical and health concerns. While conventional laboratory-based testing remains prevalent, the appeal of routine use of low-cost and near-patient diagnostic systems opens up potential avenues for rapid disease screening, longitudinal medication effectiveness studies, biomarker discovery, and prognostics. In this research seminar, Dr. Salahandish delves into the scientific underpinnings and outcomes of her doctoral and postdoctoral research, as well as her ongoing investigations into novel technologies for biomedical devices, with a specific focus on wearable diagnostic platforms. This includes the fabrication of compact and multiplexed electrochemical biosensing systems, utilizing screen-printing of chemically engineered nanomaterial inks, or developing nanocomposite interfaces to detect disease-related proteins, RNAs/DNAs, and metabolites. Additionally, Dr. Salahandish will discuss the integration of biosensing strips with microfluidic systems to enable automated on-chip assay performance, as well as the development of impedance-based bi-potentiostats as custom-made handheld readout systems. The combination of these technologies creates a portable quantitative diagnostic platform. Although the clinical applications of electrochemical sensing are still in the early stages of validation, there are promising research opportunities in utilizing these biosensors for rapid detection of multiple biomarkers, wearable and in-vivo biosensing patches and chips, and tissue modeling organ-on-a-chip systems for drug discovery purposes. These advancements hold great potential in both academic and industrial realms for breakthrough developments in the future.
