Hello,
We have looked at the Optical Scattering off a Gold Nanosphere model (model 12415) after
trying on our own to solve for the frequency response of a gold nanosphere. We also attempted modifying the Radar Cross-Section model (model 8613) for the same purpose. Both models must use an electrical conductivity of zero for the gold in order to obtain the correct result. We do not understand why this is so, since the electrical conductivity of gold is nonzero.
More generally, when is it appropriate to set electrical conductivity to zero and when is it not?
