In this talk, we intend to provide a brief overview of electromagnetic selective surfaces/structures (EMSS). According to the properties of an incident electromagnetic wave, EMSS can be divided into four categories: frequency-selective structure (FSS), polarization-selective surface (PSS), angle-selective surface (ASS), and energy-selective surface (ESS). Recent developments and advances in the design of EMSS will also be briefly introduced. Finally, future opportunities in the areas of the design and analysis of EMSS will be suggested.

Please join us for an upcoming talk on Jul 06, 2-3pm (Eastern Time) by Prof. Emily Porter titled "Microwave Medical Technologies: Foundations and Clinical Applications," as part of the 2021-2022 IEEE AP-S seminar series. Abstract: Microwave medical technologies have promising potential for applications spanning health monitoring, detection and diagnosis of disease, and even treatment. These technologies are low-cost, non-/minimally-invasive, non-ionizing, safe and well-tolerated, and can be made wearable or portable. In this talk, the motivation and basic foundations of microwave techniques are discussed, followed by the challenges of designing high quality basic research to support such medical device development. Key factors influencing the design and development of next generation microwave medical devices will be discussed. In particular, the difficulties faced when measuring and reporting the dielectric properties of biological tissues are emphasised, focusing on the importance of achieving accurate and representative measurements. Promising microwave-based medical technologies designed to address high-priority clinical needs will be highlighted. Lastly, proposed future activities in this area will be discussed. About Speaker: Dr. Emily Porter is an Assistant Professor with the Department of Electrical and Computer Engineering at The University of Texas at Austin, where she is associated with both the bioECE and Electromagnetics & Acoustics research areas. Dr. Porter was granted her Ph.D. in 2015 from McGill University, Montreal, Canada. She also has an M.Eng. and a B.Eng. in Electrical and Computer Engineering, completed in 2008 and 2010, respectively. More recently, Dr. Porter was an NSERC Postdoctoral Fellow and then an EU Marie-Curie Research Fellow with the Translational Medical Device Laboratory at National University of Ireland Galway, from 2015-2019. In 2021, she was awared the IEEE Lot Shafai Mid-Career Distinguished Achievement Award for her contributions to microwave medical technologies, standardizing the methodology for measuring the dielectric properties of biological tissues, and advocating for women in engineering. Her research interests lie in applied electromagnetics, and particularly aimed at developing electromagnetic (EM)-based solutions with applications in diagnostic, therapeutic, supportive or assistive medical technologies.

The extension of power grid interconnection with an increased amount of power flow control, the long-distance transmission, and the integration of large blocks of wind, solar and hydro powers all call for the accelerated development of high voltage direct current (HVDC) transmission. Despite the opportunities such as lower power loss, higher capacity for a fixed corridor, fully controllable power flow, better transmission and stabilization capabilities between non-synchronized AC power systems, and no length restriction because of free reactive power compensation, there are still significant technical challenges for HVDC cabling systems. The electric field distribution under DC voltage in the cylindrical cable insulation initiates with the Laplacian electric field distribution; however, the thermal gradient (TG) across the insulation and the change of the electrical conductivity because of its temperature dependence under loading conditions will lead to the phenomenon of electric field inversion across the dielectric. In addition, the electric field distribution across a DC cable insulation is affected and often distorted by the accumulation of space charge. Therefore, controlled electrical conductivity and highly suppressed space charge accumulation are desired for tailoring the electric field across the cable insulation under DC. Full characterization and detailed understanding of these properties as well as their correlation may bring the ability to engineer needed dielectric properties for using as DC cable insulation. With respect to implications for practical material design, the study demonstrates that a polymer material with activation energies in the range of 0.4 to 0.5 eV with relatively high trap density can be suitable for HVDC cable insulation. The mass-impregnated (MI) insulations have been used traditionally for DC cabling systems with line-commutated converter (LCC) schemes. The MI insulations produced by a lapping process could be considered as a layered composite structure with excellent performance under polarity reversal condition which is essential for changing the direction of power flow in LCC systems. Compared with MI insulation cables, polymeric insulations such as crosslinked polyethylene (XLPE) insulations are lighter, less expensive, and less harmful to the environment compared with MI insulation cables and can be manufactured by continuous extrusion process and conveniently extended during installation by oil-free pre-molded joints. However, DC cables with XLPE insulation are only applicable for the voltage source converter (VSC) systems. Therefore, there still exists the need for insulation with the advantages of both MI and polymeric insulations, i.e., an extrudable insulation that is compatible with polarity reversal. A model DC material based on the ethylene propylene rubber (EPR) incorporated with 2D inorganic nanoclays is proposed. The DC electrical properties of the proposed material show large improvement in space charge suppression, controlled electrical conductivity and consequently more uniform electric field distribution. Microstructure studies suggest the uniform and oriented distribution of 2D nanoclay particles in EPR matrix causes a desired trap distribution with high density of shallow traps due to the presence of a high interfacial area between polymer chains and nanoclay particles. The macroscopic effect of that is a significant reduction of activation energy which contributes to controlling the charge transport and suppressing the space charge accumulation in the composite dielectrics. Results of the thermally stimulated depolarization current spectra of the samples are in good agreement with the predicted trap distribution based on the experimental results and morphological study.

Microgrids integrating RES and ESS are increasingly being deployed across the world. Isolated and grid connected microgrids require control and protection systems to ensure optimal power sharing, storage management, maintaining required power quality, stability, resiliency and reliability of supply. The main focus of an ongoing Indo-US joint project ‘UI-ASSIST’, involving 15 consortia partners from US and India, is to develop models including pilot demonstrations for future smart distribution networks integrating RES, ESS and microgrids. This talk will briefly discuss the technical details and challenges faced in setting up these pilots.
