Tuesday, May 15th at 4:00 p.m., Prof. Andy Marvin, IEEE Life Fellow and Fellow of Royal Academy of Engineering, will be presenting “Shielded Enclosure Metrics”. Day & Time: Tuesday, May 15th, 2018 4:00 p.m. ‐ 5:00 p.m. Speaker: Prof. Andy Marvin IEEE Life Fellow, Fellow of Royal Academy of Engineering Professor Emeritus, Department of Electronic Engineering, University of York, York, UK. Location: Room BA2185, Bahen Center of Information Technology 40 St. George Street, Toronto, ON M5S 2E4 Contact: gelefth@ece.utoronto.ca Organizer: IEEE Toronto Electromagnetics & Radiation Chapter Abstract: The lecture describes the author’s research over the past decade investigating better ways of defining and assessing the shielding performance of equipment enclosures. The definition of enclosure Shielding Effectiveness and its limitations are reviewed. Then recent research on the use of surrogate contents to replicate real electronic enclosure contents is described leading to alternative definitions of enclosure shielding performance. Latterly, the work has concentrated on shielding of equipment enclosures in the microwave frequency range. Measurement techniques exploiting the reverberant nature of the enclosures are described. The work has contributed to the recently released IEEE Std 299.1 on the measurement of equipment enclosure shielding. The HUAWEI Corporation has sponsored the research since 2014. Biography: Andy Marvin is Professor Emeritus in the University of York’s Department of Electronic Engineering. He received his BEng, MEng and PhD degrees in Electrical and Electronic Engineering from the University of Sheffield between 1972 and 1979. From 1977 to 1979 he was with the British Aircraft Corporation at Filton, Bristol, UK working on antenna design and EMC. He was appointed to a Lectureship in Electronics at the University of York in the UK in 1979 and promoted to Professor of Applied Electromagnetics in 1995. He retired in December 2017 and was appointed as Professor Emeritus in February 2018. He was appointed as Technical Director of York EMC Services at its founding in 1995. He resigned his directorship when the company was acquired by Eurofins in June 2017. He is a Fellow of the Royal Academy of Engineering and an IEEE Life Fellow. He was Vice-Chairman of the IEEE Std-299 Working Group on Shielding Effectiveness Measurement, and is currently Vice-Chairman of the IEEE EMC Society Standards Advisory and Co-ordination Committee. From 1994 to 2015 he was an Associate Editor of IEEE Transactions on EMC. He was a member of the UK National Measurement System Advisory Panels on Innovation Research and Development and Materials and Modelling from 2008 to 2015. He has contributed lectures on Antennas and on Shielding to the IEEE EMCS Global University and Chaired its Faculty in 2010. His main research interests are EMC measurement and modelling techniques, EMC antennas and electromagnetic shielding measurement and modelling. To date, starting in 1976, he is author over 300 papers. In 1992, he and Dr Stuart Porter invented the Bilog EMC measurement antenna. He is a founder member of the International Steering Committee of EMC Europe conferences, Conference Chair of EMC Europe 2011 (York) and Chair of the EMC Europe International Steering Committee for 2015 – 2018. He was President of the York Society of Engineers (2014/16) and is Chief Flying Instructor at the York Gliding Centre.

Thursday, May 31st at 4:00 p.m., Dr Yongxin Guo, National University of Singapore, Singapore, will be presenting a distinguished lecture: “RF in Medicine: Current Status and Challenges of Antennas and Wireless Power”. Day & Time: Thursday, May 31, 2018 4:00 p.m. ‐ 5:00 p.m. Speaker: Dr Yongxin Guo National University of Singapore, Singapore Location: Room Number: BA 1180 Bahen Centre for Information Technology 40 St George St, Toronto, ON M5S 2E4 Contact: George V. Eleftheriades Organizer: IEEE Toronto Electromagnetics & Radiation Chapter Abstract: Wireless power and data telemetry technologies for biomedical and healthcare applications have received a lot of attention recently. Numerous applications in medical diagnostics and therapeutics ranging from cardiac pacemakers to emerging devices in visual prosthesis, brain computer interfaces and body area networks have spurred electronic engineers to propose new wireless medical devices. In the meantime, the ageing population poses many challenges to healthcare systems, especially on chronic illness management. In this talk, I would mainly cover our recent research progress on wearable/implantable antennas and wireless power for biomedical applications. A few related ongoing biomedical projects for on-body and in-body applications will be addressed. In addition, I would also briefly introduce my other related research activities. Biography: Yong-Xin Guo received his Ph.D. degree from City University of Hong Kong in 2001. From September 2001 to January 2009, he was with the Institute for Infocomm Research, Singapore, as a Research Scientist. He joined the Department of Electrical and Computer Engineering, National University of Singapore (NUS), as an Assistant Professor in February 2009 and was promoted to a tenured Associate Professor in Jan 2013. He has authored or co-authored 206 international journal papers and ~200 international conference papers. Thus far, his publications have been cited more than 6200 times and the H-index is 44 (source: Google Scholar). He holds 8 granted/filed Patents in U.S. or China. His current research interests include antennas for wireless communications and biomedical applications, wireless power for biomedical and IoTs, and MMIC modelling and design. He has graduated 12 PhD students at NUS. Dr Guo was the General Chair/Co-Chair for AWPT 2017, ACES-China 2017, IEEE IMWS-AMP 2015 and IEEE IMWS-Bio 2013. He served as a Technical Program Committee (TPC) Co-Chair for IEEE IMWS-AMP 2017 and RFIT2009. He is serving as Associate Editors for IEEE Journal of Electromagnetics, RF and Microwave in Medicine and Biology, IEEE Antennas and Wireless Propagation Letters, and Electronics Letters. He was a recipient of the Young Investigator Award 2009, National University of Singapore. He received 2013 Raj Mittra Travel Grant Senior Researcher Award. He is an IEEE Fellow.
