  • There are a lot of interaction phenomenon between electromagnetic wave and plasmas. In this paper, propagation characteristics of electromagnetic wave in unbound periodic and magnetized plasma are strictly analyzed in theory, and the dispersion equation is obtained. By numerical calculation, the affection of change of plasma background density and the sinusoidal variation amplitude value of plasma density on propagation characteristics of electromagnetic wave is analyzed. The results of calculation presents that the effect of change of plasmas density on two characteristic wave (right hand wave and left hand wave) is different. The change of sinusoidal amplitude value of plasma density has a poor effect on the cut off frequency of right hand wave and left hand wave, however, plasma background density has a big effect on the cut off frequency of right hand wave and left hand wave. Meanwhile, this system is a periodic slow wave system in which slow wave is found and may make some important effects on bean-wave interaction.

Abstract: There are a lot of interaction phenomenon between electromagnetic wave and plasmas. In this paper, propagation characteristics of electromagnetic wave in unbound periodic and magnetized plasma are strictly analyzed in theory, and the dispersion equation is obtained. By numerical calculation, the affection of change of plasma background density and the sinusoidal variation amplitude value of plasma density on propagation characteristics of electromagnetic wave is analyzed. The results of calculation presents that the effect of change of plasmas density on two characteristic wave (right hand wave and left hand wave) is different. The change of sinusoidal amplitude value of plasma density has a poor effect on the cut off frequency of right hand wave and left hand wave, however, plasma background density has a big effect on the cut off frequency of right hand wave and left hand wave. Meanwhile, this system is a periodic slow wave system in which slow wave is found and may make some important effects on bean-wave interaction.
