Abstract

We study the resonant excitation of the electromagnetic modes in a planar waveguide of metallic walls - light incident on the guide from the air can transfer energy through the walls exciting normal modes of propagation. It is found theoretically that radiation propagates along the guide while the reflectivity presents a minimum. The energy of the incident radiation can be transferred to the guide almost completely when the thickness d_m of the metallic wall is around two times the skin depth. Experimental evidence of the injection of light is presented for the system Ag/Al₂O₃/Ag that was grown by pulsed laser deposition.
