摘要：
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 IIR design. It is shown that the numerical results are consistent with analytic solution.
