Investigation of the THz radiation propagation in hyperbolic graphene-semiconductor metamaterial is presented. Anisotropy of the hyperbolic media slab was taken into account. The 4×4 Berreman matrix method was adopted for arbitrary orientation of optical axis according to slab boundary.
We are carefully analyse the properties of the eigenwaves of 2D-structure with regularly ordered metal nanorods in lossless dielectric. Plane-wave-decomposition was used in numerical calculations. New ”hyperbolic” solutions were found.
We have shown that the characteristics of propagation of optical radiation in a photonic-crystal fiber that contains semiconductor elements can be controlled by external radiation that acts on the structure. We have studied a photonic-crystal fiber that is formed by air holes in a dielectric that contains a semiconductor (GaAs) tube in the central region (core region) filled inside with the same dielectric...
The properties of new optical waveguides with nanosize cross-section made of noble metals and glasses are described. This waveguide supports propagation of modes with unusual propagation properties. The comparatively low value of losses has explained.
In this paper we investigate the field propagation characteristic in new type new optical waveguides, made of glasses and noble metals. The proposed waveguide, having nanosize cross-section, supports propagation of modes with unusual propagation properties. The propagation speed, attenuation and field localization of those modes will be present. The proportional reducing of the coaxial scale have...
