THE EIKONAL EQUATION IN A MOVING MEDIUM.

Abstract

The eikonal equation as derived by Sommerfeld and Runge has been extended to include the case of moving media under the condition where v/c << 1 (v is the velocity of the medium, c is the speed of light in vacuum). Using the Hamilton Jacobi formalism, the equivalent system of linear equations was determined which can be used for ray tracing. An example of a moving medium where the index of refraction is a function of one of the coordinates has been considered. (Author)
