Abstract:In this paper, a novel design of polarization selective surface (PSS) is proposed for co‐channel interference (CCI) suppression. By establishing a switchable doublet topology, two types of second‐order filtering responses with two transmission zeros are generated under TE and TM polarizations. The PSS element is composed of a combined dual‐mode resonant cavity. Meanwhile, the coupling matrix provides guidelines for PSS design. Moreover, detailed analyses of polarization angles account for CCI suppression. Fina… Show more
