“…According to inequalities (7,8) in general case, the absorption parameters have an influence on conditions of backward wave propagation and anomalous refraction. In particular, these phenomena can not take place for the nonabsorbing medium and "switch on" only in the presence of absorption.…”

“…At investigations of effectively anisotropic metamaterials (MM) the following assumptions are frequently used: absence of optical absorption or losses, electromagnetic wave homogeneity allowing usage of refractive index and wave vector surfaces, linear polarization of the incident radiation (see, e.g., [1][2][3][4][5][6][7] and references in these works). Moreover, for uniaxial MM it is often assumed that the optical axis is parallel or perpendicular to MM layer boundaries and cases of diagonal permittivity or (and) permeability tensors are considered [1][2][3][4][5][6][7] .…”

Features of the polarization, energy fluxes of proper inhomogeneous electromagnetic waves in a layer of absorbing uniaxial negative index metamaterial, and an exact solution of the corresponding boundary problem are investigated. A comparative analysis and modeling of optical properties of anisotropic conventional media and metamaterials is carried out. Conditions and possible advantages of a controlled transformation of the radiation characteristics by the metamaterial are analyzed.

“…Nowadays, production of isotropic magnetic MM is a complicated technological problem. On the other hand, at investigations of MM the assumptions are frequently used: absence of optical absorption, electromagnetic wave homogeneity allowing usage of refractive index and wave vector surfaces, linear polarization of the radiation, and analysis of only TM (TE) waves in MM (see, e.g., [1][2][3][4][5][6][7][8][9] and references in these works). Moreover, as a rule, only the simplest cases of anisotropic MM are considered.…”

Boundary electrodynamic problem for a layer of effectively uniaxial absorbing metamaterial (MM) is solved. Proper inhomogeneous waves in the layer are neither TM (TE), when the optical axis is non-parallel to the incidence plane, nor purely evanescent. Features of excitation of particular waves with linear amplitude dependence on coordinates in MM are considered. Effect of small dielectric (magnetic) anisotropy and absorption of MM on imaging properties of the Veselago-Pendry lens is analyzed. It is shown that presence of a small anisotropy is a limiting factor much stronger than small losses, and careful account of effective permittivity (permeability) anisotropy for "superlens" devices is required.

Fraunhofer diffraction of an electromagnetic wave by a slit on an opaque screen located between vacuum and an anisotropic medium with closed and open wave vectors surface is considered. A formula for diffraction in a material medium is obtained, including the case of diffraction into a uniaxial anisotropic medium in the absence of absorption, and the formation of diffraction minima and maxima is studied.
