The European Defence Agency Workshop “Radar Signatures & EM Benchmarks”: A scientific forum for comparison and evaluation of electromagnetic simulations

The workshop “Radar Signatures & EM Benchmarks” has been established by the European Defence Agency (EDA) in 2017, with the aim of bringing together scientific experts in the field of electromagnetic scattering simulations, specifically in the context of radar signatures. The 3^rd workshop was held in 2023, and a few months prior to the workshop, several test cases were published on the workshop’s webpage, which served as benchmarks to compare results obtained by different simulation codes. It turned out that such activities are extremely important for the community, both for the comparison of simulation results and evaluation of tools as well as for the interesting discussions among the leading experts in the field. This paper will provide insights into the workshop by presenting some of the recent test cases and showing some exemplary evaluation of the data computed by the participants.
