An application of equivalent transformations for analysis of nonuniform transmission lines

The author presents an efficient method of equivalent transformations for analyzing the stationary phenomena in a system of distributed-parameter circuits with jump heterogeneity and arbitrary boundary conditions. A change of the electrical line-length and a transposition of the independent sources along the line lead to an elementary lumped circuit which allows for a simple description of the phenomena in the original system. The method makes it possible to reduce a system of lumped and distributed parameters to an elementary lumped-parameter circuit consisting of active two-terminal networks. The method can be applied to the analysis of a system of interconnected active and passive uniform lines and lumped elements
