The equation of motion of the photon in an optical medium

V.P. Torchigin, A.V. Torchigin

We show that the equation of the photon motion coincides with the eikonal equation on the assumption that the photon momentum in an optical medium increases by n times compared with that in free space and the density force applied to the photon is determined by the density force derived by the Maxwell for the force in the dielectric located in an electrical field.
