Spectral Green's Function for SPR Meta-Structures

Iovine, Renato; La Spada, Luigi; Tarparelli, Richard; Vegni, L.

Abstract

In this paper we propose a new approach to study the electromagnetic field in Surface Plasmon Resonance (SPR) meta-structures. The geometry is a planar structure infinitely extended with a pulse excitation current embedded in the substrate. The general solution has been applied to a specific geometry that is frequently employed to model practical problems. The minimization of the thickness changes spectral Green's function in a more efficient form, suitable for calculations. Plasmon electric field expression on interface plane is obtained. This kind of meta-structures is suitable in various fields of application (e.g. optoelectronics and electromagnetic sensors).
