Electromagnetic surface waves guided by a plane interface between a porous nanocomposite and a hypercrystal

Abstract

Dispersion properties of surface electromagnetic waves localized at the plane interface between a nanocomposite made of a semiconductor inclusions evenly distributed in a transparent matrix and a hypercrystal, formed by an alternating dielectric and hyperbolic layers are studied. Electrodynamic Maxwell Garnett model is applied to simulate the effective resonance permittivity of the nanocomposite. In the subwavelength approximation the hypercrystal is represented as the uniaxial media with two different principal permittivity tensor components. The particular attention is devoted to the study of dispersion properties of hybrid Dyakonov surface waves. It is shown that by properly choosing physical and geometrical parameters of the corresponding composites, like volume fractions of nano-inclusions, thicknesses of hyperbolic and dielectric layers, and materials used, the effective control over the properties of supported surface modes is possible.
