Joshua Le-Wei Li (SM’96-F’05) received his Ph.D. degree in Electrical Engineering from Monash University, Melbourne, Australia, in 1992. He was, as a Research Fellow, with Department of Electrical & Computer Systems Engineering at Monash University, sponsored in 1992 by Department of Physics at La Trobe University, both in Melbourne, Australia. Between 1992-2010, he was with the Department of Electrical & Computer Engineering at the National University of Singapore where he was a tenured Full Professor and the Director of NUS Centre for Microwave and Radio Frequency. In 1999-2004, he was seconded with High Performance Computations on Engineered Systems (HPCES) Programme of Singapore-MIT Alliance (SMA) as a SMA Faculty Fellow. In May-July 2002, he was a Visiting Scientist in the Research Laboratory of Electronics at Massachusetts Institute of Technology (MIT), Cambridge, USA; in October 2007, an Invited Professor with University of Paris VI, France; and in January and June 2008, an Invited Visiting Professor with Institute for Transmission, Waves and Photonics at Swiss Federal Institute of Technology, Lausanne (EPFL) in Switzerland. In 2010, he was invited to join School of Electronic Engineering at University of Electronic Science and Technology of China (UESTC), Chengdu, China where he was selected as a QRJH Chair (or National) Professor of China, Distinguished Professor in School of Electronic Engineering, and the Founding Director of Institute of Electromagnetics and also Research Centre for Space Solar Energy Applications and Microwave Power Transmission. Currently, he is also affiliated with School of Engineering at Monash University, Clayton/Sunway, Victoria/Selangor, Australia/Malaysia where he is a Professor of Electrical & Computer Systems Engineering and Director, Multidisciplinary Program of Advanced Engineering. His current research interests include electromagnetic theory (e.g., dyadic Green’s functions), computational electromagnetics (e.g., pre-corrected fast Fourier transform – P-FFT method and adaptive integral method -AIM), radio wave propagation and scattering in various media (e.g., chiral media, anisotropic media, bi-anisotropic media and metamaterials), microwave propagation and scattering in tropical environment, and analysis and design of various antennas (e.g., loop and wire antennas and microstrip antennas). In these areas, he has (co-)authored 2 books (namely, Spheroidal Wave Functions in Electromagnetic Theory (New York: Wiley, 2001); Device Modeling in CMOS Integrated Circuits: Interconnects, Inductors and Transformers (London: Lambert Academic Publishing, 2010), 48 book chapters, over 800 technical papers published and presented, with 9 inventory patents filed. He has graduated over 80 Master-degree and PhD-degree students, and mentored over 20 post-doctoral fellows and research scientists.
Prof. Li was a recipient of a few awards including 2 best paper awards from the Chinese Institute of Communications and the Chinese Institute of Electronics, the 1996 National Award of Science and Technology of China, the 2003 IEEE AP-S Best Chapter Award when he was the IEEE Singapore MTT/AP Joint Chapter Chairman, and the 2004 University Excellent Teacher Award of National University of Singapore, and the 2011 Outstanding Professorship Award by UESTC School of Electronic Engineering. He has been a Fellow of IEEE since 2005 and a Fellow of The Electromagnetics Academy since 2007 (selected member since 1998) and was IEICE Singapore Section Chairman between 2002-2007. He was a Guest Editor of a Special Section on ISAP 2006 of IEICE Transactions on Communications, Japan and a Special Section on APMC 2009 of IEEE Transactions on Microwave Theory and Techniques, USA. He is currently the Editor of Radio Science, and an Associate Editor and an Editorial Board Member of a few international & regional peer-reviewed journals. He has been appointed a Commission-15 member of IEEE MTT-S since 2007, and a Region (Asia-Pacific) Representative of IEEE AP-S since 2010; and now serves as an IEEE AP-S Distinguished Lecturer (2011-2013).
Wireless Power Transfer: From Long-Distance Transmission to Short-Range Charging
Abstract – Since Nikola Tesla proposed the Wardenclyfee Tower in 1889 for the wireless power transmission to date, it has been over a century. The idea was later picked up and implemented continuously in the last half a century. Recently in 2007, MIT research group picked up the old concept and implemented for potential applications into telecommunications. This talk will address briefly the state of-the-art research and development progresses in the wireless power transmission technology and also potential applications. The talk is categorized into two aspects, that is, (a) the long-distance and high-power wireless energy transmission and (b) the short-range and low-power wireless energy transmission. For the long-distance high-power transmission, the talk will cover atmospheric effects, high-power microwave generation, transmitting antennas, EMC/EMI effects on radio frequency wireless system, rectennas, and biological effects on human being and animals. For the short-range wireless power transmission, the review will touch inductive couple effects and their applications onto power-grid systems, wireless power charging systems, mine-tunnel power charge system, and medical applications. The talk will, of course, discuss on advantages and short-comings of these proposals.
