Abstract:

A novel 3D sub-terahertz frequency selective surface (FSS) based on a dual-mode cavity resonator is presented in this paper. In each resonator unit, a pair of degenerate modes, namely TM210 and TM120, are excited simultaneously to dominate each of the dual polarizations, respectively. High isolation and cross-polarization level can be implemented due to the modal orthogonality of the proposed degenerate modes. Both channels share the common cavity resonators from the first order to the last order with specified external quality factor (Qe) and coupling coefficient (K). To proof-of-concept, a 2nd-order FSS prototype is designed, and its performance is verified in simulation. It resonates at 120 GHz with a fractional bandwidth of 6.1%. The channel isolation is better than 50 dB.
