Optimized Design of a Dual-Band Polarization Selective Surface with Third-Order Band-Pass Responses Using In-House Method of Moments
This letter proposes a procedure to design a third-order dual-band polarization selective surface (PSS) which enables the transmission of the polarization along the $x$ axis in the lower band, and the transmission of the polarization along the $y$ axis in the upper band. The PSS is a multilayered structure in which periodic arrays of rectangular metallic patches are alternated with periodic arrays of rectangular apertures. Filtering equivalent circuits are used in the design of the PSS in both bands, and an ultra-efficient in-house Method of Moments software is employed in the design process, which is possible thanks to the simplicity of the metallization patterns of the multilayered structure. A prototype containing prepreg laminates as bonding material has been fabricated and measured. After minor adjustment of the dielectric substrate parameters, good agreement has been found between simulations and experiments. The designed PSS exhibits large frequency selectivity and angular stability up to 45$^\circ$ with respect to the normal incidence direction.

Exploiting Mirror Symmetry in the 2-D MoM Analysis of the Scattering by Conducting Cylinders
In this paper the authors carry out a judicious application of the 2D Method of Moments (MoM) to the analysis of the scattering of plane waves by infinite conducting cylinders in the case where the cylinders show two orthogonal planes of mirror symmetry. In particular, the original MoM scattering problem is replaced by four new MoM scattering problems in which the two mirror symmetry planes behave as perfect electric conductors and/or perfect magnetic conductors. The current densities of the four new MoM problems only have to be obtained in one quarter of the cylinders cross-section, and therefore, the number of MoM matrix entries in each new problem is one sixteenth the number of MoM matrix entries in the original problem, which makes it possible to reduce the CPU time required for the solution of the original problem to roughly one fourth. Results are generated for cylinders where the cross section is a rectangle, a rhombus, an ellipse and an ogive, the one quarter CPU time reduction being confirmed in all cases
