Transient and Sensitivity Analysis of Uniform Multiconductor Transmission Lines via FDTD Methods

摘要

The paper deals with techniques for a computation of voltage and/or current distributions along the multiconductor transmission line (MTL) wires by means of Finite-Difference Time-Domain (FDTD) methods. Besides the basic methods are extended to enable sensitivities determination useful for gradient-based optimization techniques. All computations are done in the Matlab language environment utilizing sparse matrix notations, comparisons with state-variable and Laplace transform techniques are presented as well.
