Abstract

In the present article the SPP propagation in an attenuating medium is investigated. The analytical calculations of the total electric-field Green's tensor of a metal-dielectric interface structure are provided and novel explicit expressions for Green's tensor of a metal-dielectric interface are presented. The contribution of plasmons are obtained by evaluating the poles of the reflection coefficient for p-polarized waves incident on the metal interface. The emission pattern of a classical dipole located above air/silver interface is studied. The relative intensity of the field to the field intensity in free space is studied for both normal and parallel orientations of the dipole. The quantum optical properties of a quantum emitter coupled to a metal surface are studied. For a quantum dot near a metal surface single photon emission is demonstrated using second-order correlation functions.
