Implementation of the critical points model in the recursive convolution method for modelling dispersive media with the finite-difference time domain method

Abstract : We describe the implementation of the critical points model in a finite-difference time domain code dealing with dispersive media through the recursive convolution method. We show that this requires only minor modifications to existing codes able to take the Drude and Lorentz models into account. The use of this model of dispersion over the typical Drude–Lorentz one may be advantageous in specific cases.
