Abstract : Concerning linearily coupled longitudinal and transversal rf waves, the difficulty of separation of the transversal part to get radiation out of the plasma, and the lack of a substantial source of radiation, because these waves are representing free plasma wave modes, are discussed. It is shown that nonlinear interaction of space charge waves yields a radiation source of pure transversal waves, which at the second harmonic of the plasma frequency can run t rough the plasma and leave it. Formulae of the radiation field at large distances from the source are given and applied to the narrow band solar bursts. The observed exhibition of the second harmonic as well as the spectral energy distribution can easily be explained. (Author)
