Enhancement of four reflection shifts by a three-layer surface plasmon resonance
arXiv:1211.1050 · doi:10.1103/PhysRevA.86.055801
Abstract
We investigate the effect of a surface plasmon resonance on Goos-Hanchen and Imbert-Fedorov spatial and angular shifts in the reflection of a light beam by considering a three-layer system made of glass, gold and air. We calculate these spatial and angular shifts as a function of the incidence angle showing that they are strongly enhanced in correspondence of the resonant angle. In particular, we find giant spatial and angular Goos-Hanchen shits for the p-wave light close to the plasmon resonance. We also predict a similar, but less pronounced, resonant effect on spatial and angular Imbert-Fedorov shifts for both s-wave and p-wave light.
