Theory of Cross-Polarization Scattering at the Upper Hybrid Resonance

A study is made of the cross-polarization scattering by magnetic field fluctuations and the resulting conversion of an extraordinary wave into an ordinary wave in the vicinity of the upper hybrid resonance. It is shown that the scattering efficiency increases with decreasing fluctuation wavelength. It is also demonstrated that the accompanying spurious signal from the crosspolarization scattering by density fluctuations is suppressed.
