Dispersion features of bianisotropic microstrip lines governed by some magnetic symmetry groups

Abstract

The generalized exponential matrix technique in the spectral domain is used in conjunction with Galerkin's approach to examine the constitutive parameter effects in microstrip lines with multi-layered bianisotropic media in this paper. To incorporate most practical applications, the mathematical treatment here accounts for very generalized bianisotropic linear media charact-erized by four independent 3×3 con-stitutive tensors but within the confines of a realizable physical range. Numerical results are presented to show the combined effects of cross coupling governed by some magnetic symmetry groups in bianisotropic superstrate-substrate on the effective dielectric constant of dominant mode.
