Research
Takashi Ohira (ohira@tut.jp) received his PhD degree from Osaka University in 1983. He developed GaAs MMICs for multi-beam satellite transponders at NTT Yokosuka Laboratory. He created electronically steerable parasitic array radiator (ESPAR) antennas at ATR Wave Engineering Laboratories. He founded two regional chapters for IEEE MTT Society (Kansai Chapter in 2006 and Nagoya Chapter in 2010). He served as an IEEE Distinguished Lecturer from 2013 to 2015. He inaugurated the IEICE wireless power transfer annual competition championship series in 2014. He presided over IEICE Tokai Section in 2016. He is currently a Professor Emeritus at Toyohashi University of Technology. He is an IEICE Fellow, URSI Fellow, and IEEE Life Fellow.
