Nonlinear sum and difference frequency generation in an inhomogeneous magnetoplasma

Abstract

Presents an analytical study of the nonlinear generation of the sum and difference frequency components, in the current density in a magnetoplasma, due to two alternating electric fields, an electron density gradient and a temperature gradient. The results of this study have been used in investigating the nonlinear growth of sum and difference frequency waves in a magnetoplasma, when two electromagnetic waves of different frequencies are propagating along the same direction in it and, also, in evaluating the magnitude of these frequency components in the reflected wave from a magnetoplasma-free space interface when the two electromagnetic waves are normally incident on the interface.
