摘要：

In this paper, a high order accuracy Finite Difference Time Domain method was proposed for the simulation of electromagnetic waves in the Debye dispersive medium. The proposed method was based on the use of the third order Backward Differentiation scheme for the approximation of the time derivatives and the use of the fourth order Central Finite Difference scheme for the approximation of space derivatives. The stability of the present method was analyzed by using the Root-Locus method. The accuracy of the proposed method was analyzed in the case of free space and the dispersive media, in the case of plane wave and the case of a Hertzian dipole source. The proposed method offered high performance regarding the accuracy and the stability in comparison with the other methods.
