The construction of hyperbolic metamaterial for an optical spectral range

Abstract

The construction is proposed of the hyperbolic metamaterial for an optical spectral range with the expanded working range of wavelength due to periodic system of nanorods in a definite range of diameters and heights. The construction is fulfilled on aluminum-oxide ceramics with the periodic system of nanoholes with the diameters from 30 up to 50 nm filled with particles of noble metal, which forms metal nanorods with the height from 3 up to 10 diameters of nanorods from the side of the surface of dielectric substrate turned toward the source of electromagnetic radiation. To provide mechanical strength the thickness of the dielectric substrate is to be not less than 30 μm.
