A new technique for simulating nonlinear loaded lossy lines

A numerical model for simulating linear lossy transmission lines ended with nonlinear resistors is described. It based on two complementary formulations of the telegrapher´s equations and uses the Galerkin method. The proposed approach appears computationally less cumbersome than that based on the time-domain convolution method, especially when the analysis of multiconductor transmission lines is considered. Particular attention is paid to the uniqueness of the solution and to the convergence of the numerical approximation. Complementary formulations provide a powerful tool to study the convergence
