Ray tracing in gradient-index media
According to the presented method by A. Sharma[1] the vector-expression of ray tracing in gradient-index media have been derived and an error function is denned in this paper. With an example of the computation it is shown by the numerical solution of high accuracy that the regions for aptness of some analytical approaching solution which is used often are presented and discussed.
