Abstract
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.
