Abstract:
The work is a theoretical and experimental study of two particular cases of nonlinear wave interaction in a plasma column. The frequencies of the waves are of the order of magnitude of the electron plasma frequency. Ion motions are neglected. In the first part of the report, the nonlinear coupling of slow waves on a plasma column is studied by means of cold plasma theory. The quasistatic approximation is used to simplify the analysis. The case of a plasma column surrounded by an infinite dielectric in the absence of a magnetic field is also examined. The linear properties of slow waves are reivewed, and solutions are obtained for use in the nonlinear theory. The second part of the report is devoted to nonlinear scattering from a plasma column in an electromagnetic field having its magnetic field parallel to the axis of the column. In the linear regime, the plasma column exhibits series of multipole resonances. A warm plasma analysis using a scalar electron pressure and a nonuniform electron density profile is presented. Author
