Multi-conductor transmission line analysis using the generalized multi-mode S-parameter transformation

Abstract

The use of the generalized multi-mode scattering parameter transformation for the analysis of multi-conductor transmission lines is presented. The approach makes it possible to calculate the performance of a multi-conductor transmission line for arbitrary sets of coupled excitations using only one single-ended full electromagnetic analysis. A four-line coaxial line excited by sets of differential and common-mode voltages are shown as example.
