Waveform relaxation analysis of lossy coupled transmission line sets in cascade

Waveform relaxation has been shown to provide an efficient way to evaluate the transient response of transmission line systems through the generalisation of the method of characteristics. This method has been extended to the simulation of coupled transmission line sets connected in cascade. The algorithms proposed have been applied to systems with linear and nonlinear terminations and the results are consistent with those found by the time-stepping method with speed improvement of at least 75 times
