Transient Analysis for Multi-Conductor Transmission Lines Based on FDTD Method

Difference equations of multi-conductor transmission lines (MTL) were derived. Finite Difference Time Domain (FDTD) method combined with MTL theory was used to model and simulate the impacts of radius, height from the ground, distance between wires, raise/fall time of excitation source and types of wires on wires crosstalk. This study proposes the corresponding improvement scheme and has a certain reference value on the vehicle wiring harness layout and its EMC design.
