Paper Abstract

The integral equation formalism previously used by the present authors to describe scattering of monochromatic light from a few atomic dipoles on a flat metal surface is used to investigate the properties of the electric field on the sites of the dipoles. By treating the light-induced radiation from an atom in the electric dipole approximation a set of linear equations which allows us to determine the electric field on the atomic sites selfconsistently is established. The contributions to the selfconsistent field from radiative and nonradiative modes and from the excitation of surface polaritons are described. In the final chapter of our paper a number of numerical results for the case where the incident electric field is p-polarized are presented. Using dielectric data for Al a detailed analysis of the frequency dependence of the electric field on the site of one of the dipoles is undertaken.
