The forth test case regards the pulse propagation inside a dispersive medium
modeled by the depolarization factor sets [N.

A very popular method for a compact optical beam-former is to use a dispersive medium
to produce increasing time delays for incremental optical carrier wavelengths/frequencies.
Thus, the PLRC scheme for modeling a DCP dispersive medium
in the FDTD algorithm is essentially a four-step explicit procedure, and can be briefed as follows: Starting with the known values of [E.
Three dispersive medium
types, which comprise the Debye, Lorentz and Drude dispersive media, are all included in the generalized code for the Maxwell's equations.
The relative permittivity of a dispersive medium
introduced by Lorentz model in the frequency domain is given by [12, Chap.
The permittivity and permeability of the dispersive medium
are a function of frequency.
