Propagation of ElectromagneticWave Through Diffraction Structures

The problem of propagation of a plane monochromatic linearly polarized electromagnetic wave through a piecewise homogeneous dielectric structure (diffraction grating) without absorption, the characteristic dimensions of inhomogeneities is comparable with the wavelength of optical radiation or less than it. The problem is solved for the polarization. The case of conical diffraction is described, also the problem is formulated in the case of a lattice of optically anisotropic material.
