“…Based on the structure, the FSSs commonly employed in millimeter and submillimeter wave bands can be classified into three categories: single-layer [11][12][13][14][15][16], multi-layer [17][18][19][20][21][22], and 3D FSSs [23][24][25][26][27]. Due to the simplicity of production and analysis, single-layer FSSs are widely utilized, particularly in the design of sensors and conformal FSSs [28,29], wireless and satellite communication [30,31], radio telescope systems [12,32], etc.…”

We propose a bandpass frequency selective surface (FSS) with fast cut-off characteristics and low insertion loss. It consists of a compact high-frequency hybrid compression board with five metal layers, two Rogers RO4003C layers, and two F4B layers. The hierarchical fitting of equivalent circuits is utilized to analyze the FSS, which maintains angular stability for dual-polarized electromagnetic waves at incidence angles of less than 20 degrees. Under normal incidence, transmission amplitudes in the K-band exceed −0.87 dB. Furthermore, the proposed FSS achieves a roll-off rate of 87.6 dB/GHz, which can be applied in dual-frequency observing systems for millimeter astronomy.
