Long-range surface plasmons supported by the disordered nanowire metamaterials

Abstract

Considering the losses of metal and semiconductor and by obtaining exact dispersion relations of the modes, we theoretically study the propagation characteristics of surface plasmons supported by disordered nanowire metamaterials. The metamaterials are composed of disordered nanowires made of metal or semiconductor embedded into the dielectric material. In the case of the semiconductor nanowires, it is possible to considerably improve the propagation characteristics of surface plasmons supported by the system, as compared to the metallic nanowires.
