title: Range extension of surface plasmons by dielectric layers.
abstract: The propagation range of surface plasmons in thin-metal-film geometries can be considerably increased if a suitable dielectric layer is placed in parallel to the film. The results show that this range extension depends strongly on the separation between the metal film and the dielectric layer.
