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.

摘要

在这项工作中，我们对基于复杂介质的屏蔽微带线进行了分析研究。该研究旨在对印刷在双各向异性基板上的微带线中的主要混合模式特征阻抗进行数值计算。此处考虑的各向异性的特征在于介电常数、磁导率和磁电参数的全 3×3 张量。该研究基于光谱域中这种复杂介质的格林函数的推导。矩谱法 (SMoM) 和 Galerkin 程序用于求解所得齐次方程组。特别研究了双各向异性对相位常数和特性阻抗的影响。获得的结果与文献中报道的可用数据非常一致。
