11. Concluding Remarks
In the field of radio science, Japan has played an important role and has been anticipated to make a further contribution to unsolved problems. In this workshop, we had discussed new ideas and methodologies for future research and development on radio science by taking lessons from Japanese highly-accomplished professionals.
We had three interesting talks: Prof. Takehiko Kobayashi (Tokyo Denki University) introduced the accomplishments by Prof. Hantaro Nagaoka, with a central focus on how to calculate the inductance coefficients of solenoids (Nagaoka coefficient). Dr. Izumi Mikami (Taiyo Musen Co., Ltd.) presented what he had experienced through the development of SUBARU which is an 8.2-meter optical-infrared telescope at the summit of Mauna Kea, Hawaii, USA, including his anecdotes. Prof. Kiyomichi Araki (Tokyo Institute of Technology) outlined the development of the Mizuhashi/Smith chart in chronological order and gave a new circuit/antenna design method using S parameters.
Based on the talks, we had fruitful discussions to activate future research and development on radio science from the standpoint of academic interest and industrial application.
In addition, we had guided tour at NTT History Center of Technologies which is an archive of historical assets mainly comprising the NTT group companies’ huge collection of technological artifacts to be handled down to generations in the twenty-first century.
We had confirmed that many participants were interested in and got a better understanding of radio science through this workshop and tour.
