The paper discusses an extension of the ray equations of geometric optics to include diffraction effects for a wave beam propagating in a dispersive anisotropic medium. The diffraction effects are introduced through a complex eikonal function, where the complex part describes the electric field profile of the beam. The ray equations are derived using a formalism that allows for a complex wave vector but yields trajectories of wave propagation in real space.
