Wave-Energy Transfer in Time-Dependent Nonlinear Wave-Wave Interactions,
Abstract
The wave-energy transfer in a system of three nonlinearly interacting waves with well-defined phases and time-dependent complex wave-frequencies and coupling coefficients is studied. Necessary and sufficient conditions for the unidirectional transfer of wave-energy and their relation to instability are established. Also, sufficient conditions for the nonexistence of explosive instabilities are derived. Finally, results are obtained for the special case where one of the waves is intense and the wave frequencies and coupling coefficients fluctuate with time about their mean-values. (Author)
