Abstract
A FDTD general algorithm, based on the auxiliary differential equation technique, for the analysis of dispersive media is presented. The algorithm is suited for cases where materials having different types of dispersion axe modeled together. While having the same level of accuracy, the proposed algorithm finds its strength in unifying the formulation of different dispersion models into one form. Consequently, savings in both memory and computational requirements, compared to other ADE-based methods that model each material separately, are attained.
