Micro-Electro-Mechanical Systems (MEMS) are a class of miniature devices and systems fabricated by micromachining processes, which have wide applications in wireless communications, optical, and biomedical fields especially in the development of miniaturized tunable RF and microwave technologies and sensors. The fastest growing wireless communications market has and will continuously see dramatic changes in both the requirements on, and the capabilities of radios to support the wireless connections especially in future 5G technologies. Due to their excellent high frequency performance, tunable RF MEMS technologies are enabling new frontiers to support multiple communication standards in modern and next generation military and commercial applications. This talk will present the development of frequency agile and electrically tunable miniaturized RF and microwave MEMS switches and devices enabling multifunctional and adaptive radios. First, the needs and requirements for adaptive and reconfigurable frequency components in next generation wireless devices will be described, and a few new high performance RF MEMS switches based on new thin films and their applications on tunable RF technologies (e.g., phase shifter, filter, antenna) are discussed. In addition, other applications of MEMS sensors in gas sensing and biomedical pressure areas will also be briefly investigated.
Dr. Guoan Wang received his Ph.D. in Electrical and Computer Engineering from the Georgia Institute of Technology in 2006. He is currently an Associate Professor in the Department of Electrical Engineering at the University of South Carolina.
