Abstract
As known, engineering optical properties using artificial nanostructured media known as metamaterials has led to breakthrough devices with capabilities from super-resolution imaging to invisibility. One of the promising variant of the metamaterials are hyperbolic metamaterials (HMM) which possess anisotropic characteristics. Hyperbolic medium (HM) exhibits hyperbolic-type dispersion in space of wave-vectors and described by the diagonal extremely anisotropic permittivity tensor. This distinctive feature of the HM offers the challenge for multiple device applications and physical phenomena: negative refraction, epsilon-near-zero materials, superlenses, THz emission, nanoscale waveguiding, super-resolution imaging, quantum optics and many others. We evaluated a method of calculation of the wave propagation characteristics in the anisotropic two-components slab with hyperbolic type of dispersion. This method is relevant for many types of HM and allows to calculate the transmission, reflection, field distribution in the slab, the density of states and the threshold condition when active atoms or ions are embedded into medium.
