| Abstract: | In this paper, the phenomenon of band gap transmission in high temperature plasma is studied. Cold plasma has high pass property, so the low-frequency electromagnetic wave cannot penetrate plasma and propagate in it. Simulation results show that in high temperature plasma, a transmission peak will be produced in the low frequency band where the band gap is supposed to occur due to the influence of the external magnetic field and the electron temperature. Through the study of the frequency and the amplitude of the transmission peak, it is found that the frequency of the peak is related to the collision frequency and the magnetic field, and the amplitude of the peak is related to the electron temperature and the thickness of the plasma slab. The calculation formula of peak frequency is obtained by fitting the obtained data. The fitting formula is validated by the analytic solution, and the results show that the two methods are in good agreement. |
