Microwave seminar | 10 April 2025

Electromagnetic scattering on subwavelength structures has always been a subject of extensive investigations owing to fundamental challenges and applied rewards related to its maximization or suppression. In the realm of radar science, one of the challenges is enabling the detection of small objects with low radar cross sections. This will become increasingly important in the forthcoming era of massive deliveries with UAVs. We will demonstrate several superscattering devices for efficient tagging and will establish a few new bounds for electromagnetic scattering. Many of the structures, which underwent genetic optimization, are based on Split Rings, serving as resonant magnetic dipoles.
