A COMBINED FDTD/TLM TIME DOMAIN METHOD TO SOLVE EFFICIENTLY ELECTROMAGNETIC PROBLEMS

Modeling complex networks of cables inside structures and modeling disjoint objects connected by cables inside large computational domains with respect to the wavelength are two problems that currently present many di-culties. In this paper, we propose a 1D/3D hybrid method in time domain to solve e-ciently these two kinds of problems. The method, based upon flnite difierence schemes, couples Maxwell's equations to evaluate electromagnetic flelds in 3D domains and the transmission line equations to evaluate currents and voltages on cables. Some examples are presented to show the interest of this approach.
