Comparison of gold and silver dispersion laws suitable for FDTD simulations

Abstract : We show that it is possible to increase the accuracy of gold and silver permittivity description by using the Drude–critical points model rather than the widely used Drude–Lorentz model. We also show the effect of this improvement on the extinction efficiency and near-field intensity precision.
