Simulation of light propagation in an optically inhomogeneous medium

Optical inhomogeneity plays an essential role in the observation of various objects. For example, it underlies phenomena such as astronomical refraction and mirages occurrence. It is also used in optical devices: for instance, in the Luneburg lens, which is used in the radar reflector and microwave antenna. The research aim is to construct and examine the trajectory of light in an optically inhomogeneous medium using computer simulation. We derived the analytical formula of light trajectory in case of inhomogeneity along one coordinate, described the algorithm that constructs a trajectory of a beam in case of refractive index dependence on time and two coordinates, evaluated the accuracy of this algorithm and suggested methods of its efficiency maximization.
