Abstract

Effect of spatial dispersion on the classical field enhancement factors near a rough surface is studied in detail for two different types of the material medium - (i) metallic medium in hydrodynamic approximation, (ii) excitonic medium in the effective mass approximation. A general perturbation approach based on Ewald-Oseen extinction theorem is used to obtain fields to different orders in the surface roughness parameter. Numerical results indicate that spatial dispersion could have significant effect on the resonant enhancement of local fields.
