Analytical Analysis of the Plasmonic Enhancement of Resonance Energy Transfer in the Vicinity of a Spherical Nanoparticle

The enhancement factor of intermolecular energy transfer in the vicinity of a plasmonic spherical nanoparticle is calculated analytically. In contrast to other treatments, the present calculations exploit the knowledge of spectral properties of the electrostatic operator for spherical geometry. Some numerical calculations and further discussions are also provided.
