Nonlinear Processes in Plasmas.

Abstract

The discovery and elucidation of parametric instabilities and their application to the modification of the ionosphere by intense radar beams was pursued under this contract. The theory of their linear growth was developed and their nonlinear saturation mechanism worked out. Research was done on the nonlinear results of these instabilities and their application to other areas such as laser heating of pellets. The general mathematical theory underlying nonlinear phenomena continued to be developed in connection with the Korteweg-deVries equation which seems to be the prototype equation for large amplitude disturbances. Methods of obtaining a large number of exact solutions of this equation was developed.
