Abstract
A novel procedure for the FDTD formulation for dispersive media is pro posed. With this procedure, a dispersive medium is modeled as a time-i nvariant discrete system described in terms of its state-space equatio ns. These equations are suitable for direct incorporation into the FDT D algorithm, allowing the wave propagation in general nth-order linear dispersive media to be analyzed by the FDTD method.
