Silicon-based Terahertz High Frequency Metasurface Antennas

This talk will report our latest work on silicon-based terahertz (THz) high-frequency metasurface antennas. To the best of our knowledge, the proposed silicon-based THz metasurface antennas, including Fabry-Perot cavity antennas, reflectarray antennas, orbit angular momentum antennas, and leaky-wave antennas, demonstrate high performance and increase the operating frequency to over 300 GHz. These advances pave the way to address the demands for enhanced channel capacity and system integration in future 6G communication systems.

Dr. Shu-Yan Zhu received the Ph.D. degree in Electronic Engineering from City University of Hong Kong in 2019. From 2019 to 2021, he was a Postdoctoral Fellow and Research Fellow with the City University of Hong Kong. Dr. Zhu is the recipient of Gold Medal awards at the 48th and 49th International Exhibition of Inventions Geneva in 2023 and 2024, and the Best Student Paper Award (Second Prize) at the International Conference on Microwave and Millimeter Wave Technology 2025 (IEEE ICMMT 2025). He holds four U.S. granted patents and has authored or co-authored over 30 refereed journal and conference papers. He has served as the TPC Chair or Session Chair for many international conferences, including the Global Symposium on Millimeter-Waves & Terahertz (GSMM) 2024, IEEE 12th Asia-Pacific Conference on Antennas and Propagation (APCAP) 2023, Asia-Pacific Microwave Conference (APMC) 2022, and IEEE MTT-S International Microwave Workshop Series on Advanced Materials and Processes for RF and THz Applications (IMWS-AMP) 2022. He is currently an Associate Professor with the School of Microelectronics Science and Technology, Sun Yat-sen University (SYSU), China. His current research interests include terahertz (THz) antennas and nanoplasmonic devices, microwave/RF circuits, nanofabrication technology, and optofluidic laboratory-on-chip devices.
