Design and Analysis of Multiband Energy Selective Surface Based on Semiconductors

Single-Layer, All-Metallic Metasurface Filter With Nearly 90° Angularly Stable Resonance

“…E LECTROMAGNETIC metasurfaces (MS) are 2-D or 3-D periodic arrangements of subwavelength resonating unit cells (often termed "meta-atoms") that elicit their macroscopic response from the lattice arrangement, the unit cell geometry, and the material properties [1]. By controlling these features, one can tailor the phase and amplitude discontinuity, achieving various functionalities, such as frequency filtering [2]- [4], angular selectivity [5]- [7], beamforming [8]- [10], energy selectivity [11]- [13], and other phenomena and applications across the electromagnetic spectrum.…”
