Abstract:
Metamaterials are artificially created structures owning electromagnetic characteristics typical of traditional materials. The most promising metamaterials are hyperbolic media. Such systems are uniaxial materials with different signs of major components of the dielectric constant. Successful realization of such materials in optical frequency range is a metal nanowire medium formed in porous dielectric matrices by filling them with metal. The review considers the creation processes of dielectrics matrices with an ordered structure based on Al$_{2}$O$_{3}$ fabricated by means of anodization and filling of these matrices with various metals by electrochemical methods.
