Full-Wave Transmission-Line Theory (FWTLT) for the Analysis of Three-Dimensional Wire Like Structures

Abstract

This paper presents a generalized transmission-line theory, which is useful to describe the wave propagation along as well as the field coupling to almost arbitrary three-dimensional wire structures. In contrast to the classical transmission-line theory this new theory is a full-wave description based on generalized telegraphers equations. Whereas the mathematical structure of these equations is preserved, the coefficients (the per unit length parameters) are redefined in order to represent the intrinsic behavior of the wire structure. Due to the full-wave description all EM — phenomena, e.g., radiation, are taken into account. Measurements as well as MoM simulations were performed to validate the predicted data.
