Abstract – Over the last 20 years, there have been significant research and development activities on Radio Frequency Micro-Electro-Mechanical Systems (RF-MEMS) devices, circuits and systems. RF-MEMS has been recognized as an emerging technology for revolutionizing future RF designs, promising superior performance, significant size/weight reduction and lower cost. At the same time, the RF-MEMS community has faced ever-increasing competition from existing players in the market. In this seminar, we will review the fundamentals of RF-MEMS design and fabrication, discuss its weaknesses and strengths, present state-of-the-art results and propose future research directions.

Dr. Xiaoguang “Leo” Liu received the Bachelor's degree in electrical engineering from Zhejiang University, China in 2004 and the Ph.D. degree from Purdue University, USA in 2010. He was a postdoctoral research associate with the Department of Electrical and Computer Engineering and Birck Nanotechnology Center, Purdue University. He joined the Department of Electrical and Computer Engineering, University of California, Davis, in November 1, 2011. Dr. Liu has extensive experience in MEMS design, fabrication and measurement. His research interests include novel MEMS/NEMS devices, RF MEMS and high-Q tunable components for reconfigurable radio frontends, microwave, millimeter wave and THz electronics and antennas. Dr. Liu has published more than 35 refereed conference and journal papers. As a student, he was awarded the graduate fellowship from IEEE Antenna and Propagation Society.
