Abstract
In this letter, a hybrid implicit-explicit finite difference time domain (HIE-FDTD) method is developed for calculating electromagnetic wave propagation in double- dispersive media. In this method, the auxiliary differential equation (ADE) method is used to handle electrically and magnetically dispersive media. The stability condition of the proposed method is analyzed and is found to be identical with that of the traditional HIE-FDTD method. Numerical examples validate the accuracy and efficiency of the proposed method.Keywords
