Abstract

Propagation of optical radiation through media with complex dielectric constant is studied in this paper. The rigorous solution of this problems taking into account for curvature of ray trajectories caused by the inhomogeneous absorption is obtained on the basis of the ray-tracing technique. For a parabolic distribution of dielectric constant the analytical solution for a field is obtained. For this and other distributions of the complex dielectric constant such as Gaussian and power-low distribution the comparison is made for exact solutions and solutions neglecting the refraction caused by inhomogeneities of the imaginary component of the complex dielectric constant. It has been found that in the media where the imaginary component of the dielectric constant is comparable to or larger than the real component the effect of the curvature of the ray trajectories due to the inhomogeneity of the imaginary component is essential or dominate, respectively. The validity of solutions neglecting the refraction caused by inhomogeneous absorption is investigated.
