NONLINEAR CONVERSION OF ELECTROMAGNETIC WAVES TO ION-ACOUSTIC PLASMA OSCILLATIONS,
Abstract
The authors consider the self-consistant problem of conversion of electromagnetic waves with a frequency much higher than the critical frequency to ion-acoustic oscillations in a plasma assuming that a Langmuir wave is generated as the transverse electromagnetic wave decays and that the ion-acoustic wave is then generated by the Langmuir wave. The problem is solved with regard to ion-acoustic wave absorption as well as in the one-dimensional approximation. Examples of two-stage decay are given to illustrate application of the expressions derived in the paper. One-dimensional quasistationary boundary problems are also considered and solutions are given for nonlinear equations which determine the spatial distribution for the number of waves in the spectrum during the decay process.
