Surface plasmon-polaritons in anisotropic hyperbolic metamaterials

In this paper, features of generation of two types of surface plasmon-polaritons (SPPs) in optical anisotropic hyperbolic metamaterials formed by a periodic lattice of metal nanocylinders embedded in a dielectric matrix are considered. The dependencies of the group velocity and the penetration depth inside metamaterial of the generated plasmon-polaritons on filling ratio are established and analyzed. Based on the effective medium theory, the surface plasmon-polaritons generation at interface of hyperbolic metamaterials is analytically calculated and discussed.
