IEICE English Webinar Distinguished Lecturer Program Series January 2023
Study of Propagation Characteristics of Terahertz Waves in Beyond 5G
Prof.Akihiko hirata (Chiba Institute of Technology)
Profile：
Akihiko Hirata completed his B.S. and M.S. degrees in chemistry and Dr. Eng. Degree in electrical and electronics engineering from the Tokyo University, Tokyo, Japan, in 1992, 1994, and 2007, respectively. He joined the Atsugi Electrical Communications Laboratories of Nippon Telegraph and Telephone Corporation (presently NTT Device Technology Laboratories) in Kanagawa, Japan, in 1994, where he worked as a senior research engineer and supervisor. Since 2016, he has been a professor for Chiba Institute of Technology. His current research involves millimeter-wave antenna and ultra-broadband millimeter-wave wireless systems. He was awarded the 2002 Asia-Pacific Microwave Conference APMC prize, the 2004 YRP Award, the 2007 Achievement Award presented by the Institute of Electronics, Information, and Communication Engineers (IEICE), the 2008 Maejima Award presented by the Post and Telecom Association of Japan, the 2009 Radio Achievement Award presented by the Association of Radio Industries and Businesses, the 2010 Foundation Award presented by the Hoso Bunka Foundation, the 2010, 2012, and 2013 Asia-Pacific Microwave Conference APMC prize, and the 2011 Commendation for Science and Technology from the Ministry of Education, Culture, Sports, Science and Technology.
Summary：
The use of 300 GHz band wireless links is currently being considered for various use cases such as backhaul/fronthaul lines, mobile access, wireless local area networks (LANs), and body area networks (BANs) as a way of achieving ＞100-Gbit/s data rate. In order to make these use cases practical, it is necessary to evaluate the radio propagation characteristics in the 300 GHz band and build a radio propagation model at this frequency. To build a radio propagation model for each of the above use cases, we conduct various radio propagation experiments and simulations. In this lecture, I will present the results of these experiments and simulations of radio propagation in the 300 GHz band.
