An auxiliary differential equation (ADE) based weakly conditionally stable finite‐difference time‐domain (FDTD) method is presented for analysis of wave propagation in general hybrid dispersive materials. The perfectly matched layer is implemented in this novel scheme. Larger time step can be used and hence higher computational efficiency is obtained in this approach, as compared to conventional ADE‐FDTD method. Two numerical examples are included to verify the performances of the proposed algorithm. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:2489–2495, 2014
