FDTD Analysis of Nonuniform Transmission Lines Network under Incident Field Excitation

In this paper, a new model for analyzing nonuniform multiconductor transmission lines network in time domain is considered. The proposed model is based on the transmission line theory and the finite-difference time-domain (FDTD) algorithm, it allows obtaining induced currents and voltages directly on the all nodes (junctions and extremities). For this objective, and using a mathematical formulation based on the topological analysis of a network, we deduce a linear equation system which resolution leads directly to the induced quantities
