Review of surface plasmon polaritons in nanostructured metamaterials

Abstract

Herein, we discover the new kinds of surface wave on nanostructured metamaterial (MM), crossing the light line with a substantial portion at lower frequencies lying above the free space light line. Interestingly, the propagation of such surface waves is found to be sensitive to the parameters of the materials employed in nanostructures. Furthermore, the Ferrel-Berreman modes are observed under the certain conditions, opening a gateway towards device fabrications
