ABSTRACT
In this work, we have carried out an analytical study of a complex medium-based shielded microstrip line. The study aims at a numerical calculation of the dominant hybrid mode characteristic impedance in the microstrip line printed on a bianisotropic substrate. The herein considered anisotropy is characterized by full 3×3 tensors of permittivity, permeability and magnetoelectric parameters. The study is based on the derivation of the Green’s functions of such a complex medium in the spectral domain. The Spectral Method of Moments (SMoM) and the Galerkin’s procedure are used to solve the resulting homogeneous system of equations. The effect of the bianisotropy on the phase constant and the characteristic impedance is particularly investigated. Obtained results are in good agreement with available data reported in literature.
