Resonant excitation of surface modes at a single flat uniaxial–metal interface

Mostrar todas las versiones(2)

A theoretical study about the propagation and resonant excitation of surface modes at the flat interface between a uniaxial crystal and a metal is performed. We show the existence of a class of surface modes that, under adequate conditions, and contrary to what happens for isotropic interfaces, can...
