Abstract :
In this work, an alternative formulation of the Shift Operator Finite-Difference Time-Domain method is proposed for the analysis of general dispersive media; in this formulation, the expression of the time derivative depends on the order of the dispersive material. This method is applied then to magnetized ferrite and simple efficient equations were obtained. The dispersion characteristic of a fineline with a composite ferrite-dielectric substrate is calculated to validate the proposed formulation.
