Abstract
In this paper a new general numerical algorithm for the simulation of heterogeneous dispersive structures is presented. The general algorithm is based on the ADE-FDTD approach. It finds its strength in the simulation of cases where different materials with different dispersion types are present. Several numerical examples are presented and results are compared to analytical solutions. While having the same level of accuracy, the proposed algorithm offers savings in both memory and computational requirements, compared to other ADE-based methods.
