Abstract

The existence of a comnlex pole of the reflection coefficient of a metallic plane, or of the zero order efficiency of a metallic grating, implies the existence of a homogeneous solution of Maxwell equations. Such a solution, which exists in the absence of any incident wave, is a guided wave on the plane or corrugated surface and is responsible for several strange phenomena such as grating anomalies, total absorption of light by a grating, or the coupling of a laser beam into an optical waveguide by means of a photoresist grating. For TM polarization, the guided wave is usually due to plasmon resonance in the metal. But similar phenomena can be observed for TE polarization provided one superimposes a dielectric overcoating with convenient thickness on top of the metallic grating.
