摘要：

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. Finally, to verify the design, the PSS prototype is fabricated and tested. Measured results are in good agreement with simulations. The CCI suppression is demonstrated at two frequency bands with the highest suppression level up to 42.6 dB.
