Design of a polarization selective surface for co‐channel interference suppression
Electronics Letters, 2022 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 ...
