Finite‐difference time‐domain (FDTD) schemes based on the bilinear z ‐transform are introduced for modelling time‐domain wave propagation in dispersive Drude‐critical points media. The accuracy and efficiency of the proposed technique are verified by comparisons with other FDTD algorithms and analytical solutions.
