Kyoto University)
1. Summary
The Commission D internationally promotes research and reviews new developments in:
1. Electronic systems that push beyond current frontiers.
2. Microwave, millimeter wave and THz devices, circuits and systems
3. Nanotechnologies and nanoelectronics
4. Combined and hybrid photonic and electronic systems.
5. Photonic devices, systems, and their applications.
6. Photonic signal processing schemes, regardless of frequency of signal processed.
7. Optoelectronic systems, plasmonics, and electro-optics
8. Physics, theoretical modeling, and numerical simulation of all of the latter
The Commission focuses on electronics and photonics devices, circuits and systems for the purposeof implementing either previously inaccessible functionalities or of improving the performance ofcurrent electronic-only or photonic-only technologies.
In Japan, we also promote the research and reviews new developments in the electronics andphotonics. In period of 2021-2023, 2 Japanese professors, Prof. Naoki Shinohara and Prof. Atsushi
Kanno, contributed the activities of the Commission D as a chair and as a vice chair, respectively. We,Japanese, also contributed the flagship conferences of the URSI General Assembly and AT-AP-RASC
as session conveners and speakers. In Japan, there are some domestic conferences and workshops
related to the Commission D and they are very active. Domestic Commission D of the URSI supports
both the international activities and domestic activities.
