Abstract : Investigated was a very important mechanism for the decay of upper hybrid waves into electron Bernstein waves. This mechanism operates only in a very narrow resonance region around the harmonics of the electron cyclotron frequency. The researchers calculated the width of these resonances and compared the analytical results with experimental observations. They found very good agreement with all available data. They found a simple mechanism for the generation of upper hybrid waves from the pump made by direct conversion. Simple estimates indicate how extremely large amplitude waves can be generated.
