New TLM Algorithm Formulations for Modeling Lorentz Medium
Abstract
In this paper, we present a Transmission Line Matrix (TLM) algorithm improved by the symmetrical condensed
node (SCN-TLM) technique for simulating EM wave interactions with a Lorentz dispersive media.The proposed algorithm
is based on the use of the polarization current in the media and combines the auxiliary differential equation (ADE) technique
to manage scattering following the conventional discretization process. The number of operations requiredhas been reduced
for each iteration. The effectiveness and precision of this method are validated through the alignment observed between the
computed New ADE-TLM reflection coefficient and the analytical solutions in a Lorentz medium.
