1. Summary
We have regular commission meetings for information exchange. URSI-F has organized monthly
meeting, where we have oral presentations on electromagnetic wave propagation and remote sensing.
The time for questions and discussion is unlimited, to have very intensive discussions. Due to COVID19, we suspended most of the meetings in 2020, but we plan to have it online.
