Numerical results or multiconductor transmission line networks
Abstract
This report describes the algorithms and numerical results for a lossless multiconductor transmissionline network which is excited by a number of lumped voltage and current sources located on the transmission lines. As opposed to previous analyses of multiconductor transmission lines, the method described in this report is capable of treating networks which contain one or more closed transmission line loops. The formulation of this analysis involves defining a large matrix equation (the BLT equation for currents incident on each of the junctions of the transmissionline network. Matrix inversion then provides the solution for these incident currents, with the reflected current component then being determined from knowledge of the scattering properties of the junctions. The total junction currents are then found by combining the incident and reflected components. To illustrate this approach, a singlewire network and a more general multiconductor transmissionline network are considered with numerical results for the voltages at points within the networks displayed.
