Nonlinear theory of surface electromagnetic wave excitation in a dielectric medium by relativistic electron beam

A problem of the excitation of nonlinear surface electromagnetic waves on a plane dielectric-vacuum interface by a relativistic electron beam, travelling above the surface of a dielectric, is solved. Nonlinear field equations and boundary conditions for them are obtained for condition of strong magnetization of the electron beam. Steady-state values of amplitudes of monochromatic surface waves, excited by the beam, are found, and radiation energy fluxes and the efficiency of transformation of beam energy into radiation energy close to the saturation threshold are calculated
