Abstract:

A study of wave-wave interactions in plasmas is made using a lagrangian formulation developed by Low. Coupled mode equations are derived. The method offers distinct advantages over the conventional appraoch starting from the Vlasov-Maxwell equations. Two examples of the Lagrangian method are considered 1 the nonlinear interaction of transverse waves in a warm field-free plasma to produce plasma oscillations and 2 the interaction of three electromagnetic waves in a cold magnetized plasma. Its application to waves in warm magnetized plasmas and to explosive instabilies is considered in part 2. Author
