Our ongoing activities and initiatives are:

• The Second Edition of the European School of Antenna (ESoA) Course on “Characteristic Modes: Theory and Applications” will be held in Prague, Czech Republic during 24-28 May 2021. The course is jointly organized by Czech Technical University in Prague, Universitat Politecnica de Valencia, Leibniz Universität Hannover and Lund University. The course website with detailed information is available here. The course pamphlet is found here. The first version of this course, held in Valencia, Spain, received a good review by the ESoA Board, but we will strive to do even better this time!
• Convened Session “Characteristic Mode Analysis for Emerging Applications and New Structures” at the 2021 European Conference on Antennas and Propagation in Düsseldorf, Germany, 22-26 March, 2021 (Organizers: Dirk Manteuffel, Kalyan C. Durbhakula, and Fenghan Lin)
• Benchmarking activities to verify characteristic mode software tools (both inhouse and commercial), led by Yikai Chen of UESTC, China. Those interested can contact Yikai Chen for more details. Participants of a discussion on benchmarking activity at EuCAP 2017 are shown in the group photo below.

Our past activities and initiatives include the following:

• Marta Cabedo Fabres and Divitha Seetharamdoo organized two webinars, on 1 and 3 Dec 2020. Both have been uploaded to our YouTube channel. Details are given below:

Webinar on 1 Dec 2020 – https://youtu.be/wUdJ_czttLA

Unfortunately, the actual recording was of poor quality due to some technical issues, so the two speakers were kind enough to made separate recordings (of very high quality) for the uploaded version. The downside is that we lost the Q&A.
