Abstract :
For the plasma sheath formed around the hypersonic vehicle flying in atmosphere, the effects of plasma fluctuations on electromagnetic wave propagation is studied in this paper. Both the amplitude and phase of EM signal are modulated by the time-varying plasma. The propagation in the time-varying plasma experiment is designed and the modulation phenomenon is observed in the experiment.
