While the global commercialization of the fifth-generation (5G) wireless communications is gradually taking off, there is already significant interest in the next generation of wireless communications. 6G scheduled to be launched in 2030 will provide a Tbps data rate, microsecond latency, and almost unlimited bandwidth to the connectivity of numerous mobile and intelligent networks. This ultrafast transmission speed is enabled by driving the carrier frequency up to terahertz (THz) bands and developing advanced multiplexing technology to increase spectrum bandwidth and spectral efficiency.  Antennas and metasurfaces are ubiquitous and indispensable components to generate and manipulate electromagnetic (EM) waves. In this talk, Dr. Wu will introduce a few discoveries in THz antennas from 300 GHz to 1 THz, spatiotemporally modulated metasurface antennas, as well as their applications in imaging and communications.
 

Dr. Gengbo Wu is currently a Postdoctoral Research Fellow with the State Key Laboratory of Terahertz and Millimeter Waves, City University of Hong Kong (CityU). He received his B.Eng. and M.Sc. degrees from the University of Electronic Science and Technology of China, Chengdu, China, in 2015 and 2018, respectively, and his Ph.D. degree from CityU, Hong Kong, in 2021. Dr. Wu’s research interests include millimeter-wave/terahertz antennas, intelligent metasurfaces and metamaterials, and their applications in imaging and wireless communications. He has published more than 30 peer-reviewed papers in prestigious journals, including Nature Electronics, Science Advances, and IEEE Transactions series. Dr. Wu is the recipient of the 2022 IEEE Antenna and Propagation Society Fellowship (APSF), the Best Student Paper Award Finalist in the 2020 EuCAP, the Honorable Mention Award in the 2020 IEEE AP-S/URSI, and the Best Student Presenter Award in the 2019 EE Student Research Symposium, CityU. He serves as a committee member of the IEEE Hong Kong AP/MTT Joint Chapter in 2022 and 2023.
