Microwave scattering near the cut-off layer by density and magnetic field fluctuations

Abstract
The reflection and mode conversion of microwaves are investigated analytically for the case of relatively high field distortion by density and magnetic fluctuations. The polarization ratio of two extraordinary wave components is obtained. A solution of the full-wave equation is derived for the 1D cross-scattering problem. Peculiarities of cross-polarization scattered waves are discussed as well as possible applications to reflectometry of fusion devices.
