Phase and amplitude behaviour in conical diffraction near the resonant excitation of surface plasmons

Mostrar todas las versiones(2)

The efficiencies and phase shifts of light specularly reflected by corrugated metallic gratings in conical mounting are studied by means of rigorous formalisms based on conformal and non-conformal transformations. The reflected field is separated into components co- and cross-polarized with respect...
