Abstract
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 mapping the dispersion relation of surface plasmons, including the gap that, under appropriate circumstances, opens up in the reciprocal grating space.
