Nonlinear Effects in Plasma

For some time now there has been an interest in the nop. ­ linear interaction of electromagnetic waves in plasma [1,2]. But only in the last few years has the theory of nonlinear wave inter­ action effects undergone such vigorous development as to result in the formulation of clear phYSical concepts regarding the mech­ anisms of interaction. This development has been engendered by attempts to solv...
