FIG. 1.

(Color online) A sketch of an elementary ray tube in inhomogeneous anisotropic medium with an elastic ray and a family of rays nearby. and are two points on the ray used in the recurrent computation. denotes a cut from the ray tube by the wave fronts and is the cross section of the ray, which can be calculated through some geometry relation by using . is the unit vector perpendicular to , representing the direction of the ray.

(Color online) Ray traces of the elastic rotator calculated by transformation ray method, they are same as those evaluated by FEM simulation.
