Description
In this article, a compact triple-band bandstop frequency selective surface (FSS) is designed for terahertz applications. The proposed FSS is a single-layer structure. The unit cell consists of cross-dipoles featuring three distinct arms. The designed FSS offers three bandstop responses centered at 0.34, 0.39, and 0.43 THz with 10-dB stopband bandwidths of 12, 5, and 14GHz, respectively. The filter operation is elucidated using surface current densities and an equivalent circuit model. The unit cell exhibits a surface area of 0.374?00.374?0, where ?0 is free space wavelength at lower resonance frequency. The proposed FSS exhibits excellent stability in incidence angles up to 40? and 80? for TE and TM polarization, respectively.
