Summary:We present a new numerical algorithm for the simulation of dispersive media. This model named ADE-TLM is based on the transmission line modeling method with the symmetrical condensed node (SCN-TLM) and novel voltage sources and exploits the polarization current density J along with the voltage electric as well as the average approximation. We extend the proposed algorithm to media with dispersions described by multiple second-order Lorentz poles; the obtained results of the reflection and transmission coefficients are compared with analytical solutions.
