Modified transmission and reflection coefficients of nonuniform transmission lines and their applications

By employing the ABCD transmission matrix of a transmission line, we formul ate the reflection and transmission coefficients of a nonuniform line as po lynomial ratios in Z-transforms. Such formulations reveal explicit relation ship between transmission and reflection coefficients of a nonuniform line, These formulations, in conjunction with a reconstruction method, lead to t he realization of nonuniform lines from either the reflection or transmissi on coefficients. Several examples are presented to illustrate the applicati ons of modified transmission and reflection coefficients in practical circu its.
