Direct visualization of surface-plasmon bandgaps in the diffuse background of metallic gratings

When a surface plasmon propagates along a microrough grating, it interacts with the periodic plus the random roughness and emits light into the diffuse background, which can present intensity maxima called diffuse light bands. We reexamine previous studies on these bands within the framework of rece...
