Original Abstract

The paper deals with techniques for a computer simulation of nonuniform multiconductor transmission lines (MTLs) based on the implicit Wendroff and the state-variable methods. The techniques fall into a class of finite-difference time-domain (FDTD) methods useful to solve various electromagnetic systems. Their basic variants are extended and modified to enable solving both voltage and current distributions along nonuniform MTLs wires and their sensitivities with respect to lumped and distributed parameters. An experimental error analysis is performed based on the Thomson cable whose analytical solutions are known, and some examples of simulation of both uniform and nonuniform MTLs are presented. Based on the Matlab language programme, CPU times are analysed to compare efficiency of the methods. Some results for nonlinear MTLs simulation are presented as well.
