abstract = {This paper presents an ef cient equivalent circuit approach (ECA), based on a Floquet modal
expansion, for the study of the co- and cross-polarization in frequency selective surfaces (FSS) formed by
periodic arrays of patches/apertures in either single or stacked con gurations. The ECA makes it possible the
derivation of analytical expressions for the generalized scattering parameters associated with the proposed
circuit networks. Furthermore, the proposed circuit approach is an ef cient surrogate model that can be
combined with optimization techniques and arti cial intelligence algorithms for the ef cient design of FSS
structures, saving efforts in the computation compared to time-consuming full-wave simulators and tedious
synthesis (simulation-assisted) techniques. Due to the simplicity of the topology of the involved networks,
the ECA can also be advantageously used to gain physical insight. The proposed approach is applied and
validated in different FSS con gurations where the cross-pol component plays a fundamental role in the
design, as in circular polarizers, polarization rotators, and reflectarray cells.},
