A new frequency dependent finite difference time domain (FD-FDTD) method using digital signal processing (DSP) is proposed.The dispersive media is characterized as an infinite-impulse response (IIR) filter, directly leading to FDTD equations. The representation of a dispersive medium is therefore converted to a problem of digital fIR design. It is shown that the numerical results are consistent with analytic solution.
