Biography
Shenheng Xu was born in Suzhou, Jiangsu, China. He received the B.S. and M.S. degrees in Electrical Engineering from Southeast University, Nanjing, China, in 2001 and 2004, respectively. He received the Ph.D. degree in Electrical Engineering from the University of California, Los Angeles (UCLA), in 2009. From 2001 to 2004, he was a Research Assistant in the State Key Laboratory of Millimeter Waves at Southeast University. In 2004, he joined the Antenna Research, Analysis, and Measurement Laboratory at UCLA, where he worked as a Graduate Student Researcher under the direction of Professor Yahya Rahmat-Samii. He is currently a postdoctoral scholar at UCLA.
Research Interests
His research interests include novel designs of modern reflector and reflectarray antennas for advanced applications, various compensation techniques for reflector antennas, electromagnetic and antenna theories, and evolutionary optimization algorithms for electromagnetic applications.
