摘要
Computational study on the cross polarization scattering of ultrashort-pulse electromagnetic waves produced hy magnetic fluctuations is presented. One-dimensional coupled wave equations for ordinary and extraordinary modes are solved for incident unipolar subcycle pulses in an inhomogeneous magnetized plasma. It is shown that the peak frequencies in the spectral signals of the mode-converted reflected waves are determined from the Bragg resonance condition in the wave numbers of the ordinary mode, the extraordinary mode and the magnetic fluctuations for relatively short-wavelength localized magnetic fluctuations.
