Surface polaritons and Dyakonov-like surface waves in an isotropic-anisotropic nanocomposite system

Abstract

The properties of surface polaritons as well as Dyakonov surface waves at the plane interface between a nanocomposite made of doped semiconductor spherical inclusions distributed in a transparent matrix and a nanocomposite made of the identical transparent matrix but with doped semiconductor inclusions of ellipsoidal shape are studied. Electrodynamic Maxwell-Garnett model is applied to simulate the effective resonance permittivity of both nanocomposites. The nanocomposite with spherical inclusions represents an isotropic medium, while the nanocomposite with ellipsoidal inclusions can be described as uniaxial material. It is shown, that by properly choosing the physical and geometrical parameters of the corresponding composites, like the volume fractions and materials of nanoinclusions, the effective control over surface plasmon-polaritons and Dyakonov-like surface waves properties is possible.
