In nanoplasmonics, most metal devices are sub wavelength. This leads to geometrical sizes comparable to the skin-depth of electromagnetic waves at optical frequencies. Appropriate material models of the metallic bulk are hence indispensable.

Additionally, if the effective wavelength of the plasmon (a wave that relies on oscillations of the free electrons in the metal) becomes comparable to the mean free path length, spatial dispersion has to be considered.

This talk addresses the modeling and discretization of Maxwell's equations coupled to a spatial (nonlocal) dispersion law. Further, a model calibration strategy is proposed for future experiments. A comparison of simulation results with experimental data is also carried out.
