QUASI-TEM ANALYSIS OF RECIPROCAL NONRECIPROCAL PLANAR LINES WITH POLYGONAL CROSS-SECTION CONDUCTORS/

Multilayered multiconductor transmission lines with polygonal cross-se ction-perfect conductors are analyzed under a quasi-TEM approach. Acco rding to a model previously proposed by the authors, each polygonal cr oss-section conductor is modeled as a set of zero-thickness strips. Th e substrates can be lossy, and present possible gyromagnetic (longitud inal magnetization) characteristics as well as dielectric anisotropic properties. The method of moments of Galerkin is applied in the spectr al domain to analyze the model structure. Special attention has been p aid to the fast and accurate computation of spectral integrals. Thus, the possible symmetries of the Galerkin matrix are emphasized and recu rrence formulas to compute the tail integrals have been developed. (C) 1994 John Wiley and Sons, Inc.
