Surface Plasmon Resonance (SPR) refers to the coupling of light with the coherent electron oscillations on a metal/dielectric interface. The resulting field propagates along the interface only, with no field propagation perpendicular to the interface. The purpose of this experiment is to understand the resonance phenomenon and to excite a surface mode on a Gold/Air interface.
