Abstract:

The Maxwell equations and the fluid equations for a plasma are expanded in a perturbation series to investigate non-linear mixed frequency generation in a gyromagnetic medium. Neutral particles and ions are assumed to be fixed, collisions are neglected, and the Debye length is assumed to be small compared with the wavelengths of propagating radio waves. Using Fourier transforms the second order amplitudes are found and the mixed frequency energy per unit area generated by two monochromatic waves in a homogeneous slab of thickness Delta-z during the time interval Delta-t are calculated. This result is applied to the case when the interacting waves are not monochromatic and when the plasma is slightly inhomogeneous. Author
