A circuit model approach is here presented to characterize bi-dimensional arrangements of dual-polarized elements. This contribution is an extension of the physical insightful approach previously proposed by some of the authors. The main novelty here resides in the fact that the scatterer may support two different current profiles. This feature becomes crucial for the accurate characterization of multiple current practical scenarios, such as the analysis and design of dual-polarized frequency selective surfaces. In particular, we illustrate its applicability when, due to oblique incidence, both an even and an odd current profiles are excited in a crossed-slot element. © 2016 European Association of Antennas and Propagation.
