Abstract:
Using a new permittivity - defined by author (in Part I) for dielectrics with permanent polarization we will demonstrate new theorems of refraction (in Part II), more general, for three-dimensional (3D) electric field lines at the separation surface of two nonlinear and anisotropic materials with permanent polarization, which have random polarization main directions. Then (in Part three), some applications of the new refraction theorems are presented, for particular cases.
