Polarization Insensitive and Angularly Stable Adaptive Frequency Selective Surface for Automated and on-Demand Electromagnetic Shielding

IEEE Access, 2023
A new adaptive frequency selective surface (AFSS) has been presented for electromagnetic (EM) shielding applications. Passive EM shields lack reconfigurability which severely limits their application.
