COMMISSION F: Electromagnetic Metrology(November 2020 – May 2023)
Edited by Motoyuki Sato (Tohoku University)
1. Summary
Scientific research on electromagnetic wave propagation for wireless communication in urban andindoor conditions have been very active in the commission. In addition, radar and remote sensing
related works were reported in the meeting.
Due to COVID-19, in-face meetings have been limited, but we use online and hybrid methods for themeetings. It seems that the condition is recovering to the conventional situation, and re-started in-facemeetings.
