Generalization of Snell's law

We generalized Snell's law and the resulting ray parameter from the isotropic to the anisotropic case.  

 

Mathematically, this is a consequence of translational symmetry, and hence follows from Noether's theorem.  

 

It facilitates both conceptually and computationally raytracing and inversion in laterally homogeneous media but anisotropic.
