内容摘要Abstract:
Technology market forecasts high-frequency products will boost up rapidly in the coming decades not only the popular microwave electronics but also that of unreleased millimeter-wave and terahertz inventions. Scientists put hard efforts to demonstrate both feasibility and capability of the new allocated frequency spectrum by ITU from 110 to 450 GHz that can be commercialization through the introduction of emerging applications of wireless systems such as 6G communications, terahertz imaging, millimeter-wave detection and sensing, low-orbit space communications, intelligent ultra-fast wireless, green energy network, etc. In this talk, the speaker is going to introduce recent high-frequency electronic developments by other world-leading antenna research groups and share state-of-the-art antenna technologies invented at the State Key Laboratory of Terahertz and Millimeter Waves, City University of Hong Kong. Breaking through the bottleneck of PIN diode at high-frequency devices, the speaker will demonstrate some examples of using functional materials to design millimeter-wave and terahertz reconfigurable, tunable, and switchable devices including antennas, metasurfaces, polarizers, modulators, and filters.
个人简介(About the speaker):
Hang Wong received a Ph.D. degree from City University of Hong Kong in 2006. He joined the Department of Electrical Engineering in 2012 and is currently an Associate Professor and the Deputy Director of the State Key Laboratory of Terahertz and Millimeter Waves. He had several visiting professorships at Stanford University, USA; University of Waterloo, Canada; University of College London, UK; and University of Limoges, France in 2011, 2013, 2014, and 2015 respectively. His research interests include designs of wideband antennas, reconfigurable antennas, millimeter-wave antennas, terahertz antennas, functional-material antennas and related applications. He has published over 280 papers, 30 patents, and 2 book chapters, with Google citations of 7000+ and an H-index of 47. He is the chair of the IEEE Antennas and Propagation /Microwave Theory and Techniques (MTT) Chapter of Hong Kong, the IEEE APS Region-10 Representative, the associate editor of IEEE Transactions on Antennas and Propagation (TAP), and the associate editor of IEEE Antenna Wireless Propagation Letters (AWPL). Dr. Wong was the general co-chair of 2020 Asia Pacific Microwave Conference; and the general chair of 2021 Cross Strait Radio Science and Wireless Technology Conference. His contribution has been highly recognized by numerous technical awards and best paper awards at the international conferences at the countries of USA, UK, France, Korea, Japan, and China. He pioneered and was a co-inventor of L-probe dual-polarization antenna technology in 2004, magneto-electric antenna technology in 2006, and the first generation of Beidu’s handheld antennas in 2008, thin-intelligent antenna in 2013, reconfigurable-metal-liquid antenna in 2018, and programmable-terahertz meta in 2020. Parts of his antenna inventions were adopted by industry leaders to satellite navigation system, wireless sensing network, 5G MIMO base-stations, and auto-payment systems for vehicles. He was awarded the top 2% most-cited scientist by Stanford University in 2021 and 2022.
