Abstract:

This report consists essentially of two parts. In the first part the non-linear polarization currents excited by a plane electromagnetic wave in an isotropic plasma are discussed. The second part is devoted to a calculation of the radiation fields established by harmonic currents excited inside an inhomogeneous plasma half-space with linearly increasing electron density. The essential result of this work lies in a thorough examination of the most important harmonic current sources produced by nonlinear interactions between an electromagnetic wave and a plasma, and in the detailed study of an example of radiation effects from these current sources. The discussion of nonlinear current sources is rather complete and general, first as individual effects, then as a whole. The main limitation lies in the smallness of the parameters required for application of the perturbation method. However, this requirement is likely to be met in most of the physical problems encountered, and therefore, the method used does not severely limit the range of its application in real situations.
