The invention relates to the area of metamaterials of the optical region of wavelengths and can be applied for creation of artificial materials changing the features in optical region of wavelengths.
The technical task of the invention is the widening of the working region of wavelengths due to periodic system of nanorods in a definite range of diameters and heights. The hyperbolic metamaterial (10) of the invention is applicable for electromagnetic radiation in an optical spectral range. The metamaterial (10) comprises a dielectric substrate (1) having a periodic system of nanoholes (2) distributed over a surface of the dielectric substrate (1) and nanorods (4) of a noble metal (3) at least partially filling the nanoholes (2), characterized in that the nanoholes (2) have diameters (d) varying from 30 nm to 50 nm, the nanorods (4) have a height ( l ) in the range of from 3 to 10 times of the diameters ( d ), wherein the nanorods (4) are located at a surface of the substrate (1) which is exposable to a source of electromagnetic radiation (5).
