Prof. Yasuaki Monnai – Terahertz Leaky-Wave Antennas for Real World Applications
September 28 @ 4:10 pm - 5:00 pm
We discuss the implementation and application of terahertz leaky-wave antennas (LWA). A LWA is an antenna array integrated with a waveguide. It can generate a directional beam by coherently leaking a traveling wave from a waveguide into free space. It also enables dynamic beam steering enabled by frequency sweeping. These characteristics are particularly relevant for developing a low-loss, low-profile, and wide-aperture terahertz transmission systems. As a proof of concept, we demonstrate an application of LWAs to radar imaging in the terahertz range.
Yasuaki Monnai received the B.E. degree in mathematical engineering and information physics and M.S. and Ph.D. degrees in information physics and computing from the University of Tokyo, Tokyo, Japan, in 2008, 2010, and 2013, respectively. From 2010 to 2013, he was a Research Fellow of the Japan Society for the Promotion of Science. From 2010 to 2011, he was a Visiting Scholar with the University of Kassel and, in 2012, with Philipps University of Marburg, both in Germany. From 2013 to 2015, he was a Project Assistant Professor with the University of Tokyo. Since 2015, he has been an Assistant Professor with the Department of Applied Physics and Physico-Informatics, Keio University, Yokohama, Japan. His research interests include exploring wireless systems for interfacing humans, machines, and materials, and his technical areas of interest
include microwaves, terahertz waves, and ultrasound.
