Time-Periodic Metallic Metamaterials Defined by Floquet Circuits
IEEE Access, 2023 In this paper, we study the scattering and diffraction phenomena in time-modulated metamaterials of metallic nature by means of Floquet equivalent circuits. Concretely, we focus on a time-periodic screen that alternates between “metal” and &
