Nonlinear Cross Modulation in a Dispersive Magnetoplasm at Gyroresonance on Its Reflection from Free Space Interface

In this article expressions for the first and second order cross modulations (CM´s) have been obtained when an amplitude-modulated electromagnetic wave (EMW) is reflected from the magneto-plasma free space interface in the presence of an external magnetic field at gyroresonance by the rigorous kinetic approach (Boltzmann equation). The expressions thus obtained have been used to study the variations of the first and second order CM´s with various plasma parameters such as collision frequency, plasma frequency, and index of modulation.
