It is legitimate to assume that the which indicates a uniaxial crystal with its c axis in the z periodic structure of atoms in crystals leads to a periodic direction.

Other parameters are the same as those used in Fig. On the other hand, the form birefringence of a layered medium has been given by Eqs.
