Near field scattered by a dielectric rod below a metallic surface

Résumé

Scattering of a plane wave by a two-dimensional particle (i.e., a rod) below a metal surface is examined by means of a volume-integral approach based on Green's dyadic. A detailed study of the structure of the near field when surface plasmons are excited is reported. The role of image enhancement is described for p polarization. A method of measuring the dielectric constant of a metal based on the structure of the near field is proposed.
