Surface-plasmon band-gaps observed in the diffuse background of metallic gratings

Mostrar todas las versiones(2)

Due to the excitation of surface plasmons, the diffuse background of a microrough metallic grating can present intensity maxima called diffuse light bands. We reexamine this phenomenon within the framework of recent studies on photonic surfaces and show that it provides an experimental technique for...
