“…We take the same procedure as described in [11] to formulate MoM-based IEs describing the electromagnetic behavior of the problem under study. This allows deriving specialized Green's function for each particular boundary condition while the currents of the planar circuits are approximated as an expansion of basis functions.…”

“…A generic formulation for planar circuits within laterally bounded media can be found in [11], which gives a seamless transition between different lateral boundary conditions. In the case of canonical boundary shapes, the Green's function of the shielded media can be represented with quasi-analytical expressions (e.g., expansion of modes in a rectangular/circular waveguide) for which a comprehensive description is presented in [12,13].…”

Integral equation (IE) formulations solved by the Method of Moments (MoM) have been used successfully to address a vast variety of electromagnetic problems. Printed circuits embedded partially or totally in laterally bounded multilayered media such as microwave filters or planar antennas and their associated distribution networks are most efficiently treated by this technique. In the case that the structure as well as the excitation hold some symmetry requirements, simplifications may be applied on the problem leading to a considerable improvement in the reduction of computational time and the usage of resources. In this article, we have developed formulations providing theoretical background for applying different types of symmetry conditions in the framework of the MoM-based IE technique applied to printed circuits embedded in shielded multilayered media fed by coaxial lines. Additionally, a comprehensive convergence study has been performed to analyze the effect of mesh resolution and different aspectratios of the rectangular shield on the convergence rate of modal series representing the elements of the MoM matrix. Benefits of applying symmetry simplifications have been pointed out as well.
