In this talk, we begin by discussing quantum effects related to electromagnetics, such as spontaneous emission, Casimir force, quantum transport in devices, and quantum dissipations. Many of these effects have strong bearing on the future of quantum technology development. For instance, ways to predict coherence time in quantum systems can influence the development of quantum technologies, such as quantum communication, quantum computing, and quantum information. We will also briefly overview recent research in computational electromagnetics, involving deeply multiscale problems, characteristic mode analysis, A-Phi formulation to preclude low-frequency catastrophe, discrete exterior calculus, and computational imaging. They may influence the development of quantum technologies in the future.


Weng Cho Chew W.C. Chew received all his degrees from MIT. His research interests are in wave physics, specializing in fast algorithms for multiple scattering imaging and computational electromagnetics in the last 30 years. His recent research interest is in combining quantum theory with electromagnetics, and differential geometry with computational electromagnetics. After MIT, he joined Schlumberger-Doll Research in 1981. In 1985, he joined U Illinois Urbana-Champaign, was then the director of the Electromagnetics Lab from 1995-2007. During 2000-2005, he was the Founder Professor, 2005-2009 the YT Lo Chair Professor, and 2013-2017 the Fisher Distinguished Professor. During 2007-2011, he was the Dean of Engineering at The University of Hong Kong. He joined Purdue U in August 2017 as a Distinguished Professor. He has co-authored three books, many lecture notes, over 400 journal papers, and over 600 conference papers. He is a fellow of various societies, and an ISI highly cited author. In 2000, he received the IEEE Graduate Teaching Awar, in 2008, he received the IEEE AP-S CT Tai Distinguished Educator Award, in 2013, elected to the National Academy of Engineering, and in 2015 received the ACES Computational Electromagnetics Award. He received the 2017 IEEE Electromagnetics Award. He now is the 2018 IEEE AP-S President.
