Longitudinal partitioning based waveform relaxation algorithm for transient analysis of long delay transmission lines

Summary form only given, as follows. In this paper a waveform relaxation algorithm based on longitudinal partitioning is presented. This work models transmission lines as cascade of lumped circuit elements and lossless line segments, where the lossless line segments are modeled using the method of characteristics. This allows the transmission line to be divided into smaller, weakly coupled subcircuits, enabling the algorithm to converge more efficiently than existing relaxation algorithms based on longitudinal partitioning.
