Abstract

This study presents novel switchable frequency selective surface (FSS) structures using encapsulated gas plasma elements. Simulations of geometric parameter sweeps show passband performance effects, and second-order model performance is compared with measured results. Average switchable attenuation can be increased from 24 dB for a second-order structure to 44 dB by adding another FSS and plasma element layer. These results suggest that switchable large-area plasma-based structures are practical for electromagnetic shielding applications in extreme environments.
