Resonant-State Expansion of Dispersive Open Optical Systems: Creating Gold from Sand

The data contains the complex frequencies of the electromagnetic modes (resonant states) of gold and sand spheres considered in the publication, having an angular momentum l=1 . Both the exact values and the ones determined using the resonant state expansion are shown. It also contains the complex dielectric permittivity data of gold with a Drude and a Drude-Lorenz fit. These data are presented in the publication "Resonant-State Expansion of Dispersive Open Optical Systems: Creating Gold from Sand", Phys. Rev. B (2016) - http://dx.doi.org/10.1103/PhysRevB.93.075417
