Wave propagation in a hybrid electric/magnetic four-wire transmission line system

Abstract

The matrix theory of hybrid multiwire transmission lines has been laid very recently. Here, we consolidate this new subject by presenting analytical and numerical results concerning four-wire geometries. The examples offered address the interaction between a two-wire electric transmission line and a two-wire magnetic transmission line for the cases of coplanar, parallel, and perpendicular settings, where we show that mode coupling is observed only in the latter case.
