Query: Improved Drude-Lorentz dielectric function for gold nanospheres   There is an ever-increasing body of research in applying the Localized
Surface Plasmon Resonance (LSPR) of gold nanospheres for applications in the
visual part of the electromagnetic spectrum. An important aspect of this work
is the accurate representation of the dielectric function for nanospheres with
diameters less than the mean free path of the conduction electrons in the bulk
material. This paper describes the development of a modified Drude-Lorentz
dielectric functions for bulk gold, and for nanosphere. The models are
validated against previously published experimental work and are shown to be
valid for spheres of diameters of greater than 10 nm.
