A SCN-TLM approach for the analysis of Lorentz dispersive media

An approach for the analysis of dispersive media, based on a special transmission-line modelling method with symmetrical condensed node (TLM-SCN) with voltage sources, is proposed. It is used in the case of linear and isotropic Lorentz frequency dependence media. The scattering matrix of the proposed SCN is provided and the efficiency and the validity of this approach are proved by the computation of the reflection coefficients of air-Lorentz medium interfaces and the RCS of a dispersive sphere.
