"\"This paper presents a new approach for modeling nonuniform lossy transmission lines.

The Green's function of nonuniform one-dimensional problems is expanded in terms of the eigenfunctions of the uniform problem, yielding a rational macromodel that has a simple representation in the time-domain.
