Coaxial Lines and Waveguides

Abstract

In this article, we first describe the classical theory in which transmission lines are assumed to be a distributed section of series resistance and inductance as well as shunt capacitance and conductance. This model is then evolved into the telegrapher equation, which explains the wave nature of electromagnetic energy guided by a two‐conductor transmission line. Finally, the field theory of transmission lines is used to derive coaxial transmission‐line theory.
