Introduction of Reflection and Transmission Coefficients for Nonuniform Radiating Transmission Lines

In the framework of a high-frequency transmission-line theory for nonuniform lines (TLST), new reflection and transmission coefficients are derived using generalized definitions of equivalent quantities from the classical transmission-line theory. This leads to local and frequency-dependent reflection and transmission coefficients expressed in terms of matrizant elements. These quantities are needed to describe networks of nonuniform radiating transmission lines. A comparison between the currents calculated in the approach of TLST and those calculated with the aid of the new transmission and reflection coefficients shows an excellent agreement.
