Dr. Takashi Ohira completed his doctorate in Communications Engineering at Osaka University in 1983 and joined the YOKOSUKA Electrical Communication Laboratory at Nippon Telegraph and Telephone Public Corporation (now NTT) in April of the same year. From 1999 to 2007, he worked at Advanced Telecommunications Research Institute International (ATR) as a senior researcher, laboratory head, and laboratory director. Since April 2021, he has been Professor Emeritus of Toyohashi University of Technology and Specially Appointed Professor of the Research Center for Future Vehicle City.

Since joining NTT, he has been consistently engaged in research and development in the microwave field, achieving numerous outstanding results, including the development and practical application of GaAsMMICs for communication satellites Sakura 4, KIKU 6, and KIKU 8, and working to create and disseminate pioneering theories and methods. At ATR, he has focused on developing theory and the practice of analog spatial signal processing, including with the invention of the ESPA antenna.

Furthermore, since joining the Toyohashi University of Technology, he has made numerous research achievements in wireless power transmission technology, from basic theory to practical applications. He created and systematized the "generalized kQ theory," a fundamental theory of high-frequency power transmission systems, including wireless sections, which is the key to realizing in-running power supply for electric vehicles. He has developed a theory that has enabled the design of field-coupled wireless power transmission systems, which had previously been considered difficult and has succeeded in supplying power to electric vehicles while they are running, making them the first in the world to run without batteries. The theory has also been commercialized by a measurement equipment manufacturer as embedded software for network analyzers, contributing to the diffusion and popularization of wireless power transmission technology.

He has received many academic awards for his achievements, including the title of Fellow of the IEICE, IEICE's Electronics Society Award, the Best Paper Award, and the Commendation by the Minister of Education, Culture, Sports, Science and Technology. He has also been awarded the titles of IEEE Life Fellow and URSI Fellow, and his activities have been recognized worldwide.

In addition, he has contributed to IEICE activities by serving on many committees, technical commentaries in journals and other publications, and creating educational content, including articles for high school students and junior members, including as the Chairman of the Technical Committee on Microwave Research (2011) and the Tokai Section Chair (2018).

As mentioned above, his contributions to the field of electronics and telecommunications have been outstanding, and we are confident that he is a worthy recipient of the IEICE's Distinguished Achievement and Contributions Award.
