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.
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.
Propagation of plane electromagnetic waves in 1D periodic structures including the layers with both positive and negative refraction indexes is considered within the frame of the long wavelength approximation. The dependencies of the media effective characteristics (dielectric, magnetic, gyrotropic, electrooptic) on the corresponding properties and the relative thicknesses of the layers are investigated. These dependencies can have a resonant form even at a fixed frequency of radiation and it causes a specificity of the interaction of electromagnetic waves with such composite materials. The detailed analysis of electromagnetic waves form is executed for the structure formed by optically isotropic layers that corresponds to an uniaxial magnetic effective medium. Some additional opportunities of controlling optical properties of the investigated structures caused by the presence of negative refraction layers are considered.
