TM-Surface Waves along the Boundary between two Nonlinear Anisotropic   Dielectrics
  It is shown that the Maxwell's equations for surface electromagnetic TM-waves, propagating along the plane boundary between two nonlinear dielectrics with arbitrary diagonal tensor of dielectric permittivity, depending of |{\bf E}|, can be integrated in quadrature.
