太赫兹波斜入射到磁化等离子体的数值研究
Numerical study of oblique incidence of terahertz wave to magnetized plasma
摘要
Abstract
With regard to "blackout" problems in aircraft,the transmission characteristics of terahertz (THz) waves in magnetized and homogeneous plasma were studied.Within the established framework of the electromagnetic wave which is inclined to the magnetized plasma transfer model,we compared different performances of terahertz waves in the magnetized plasma,by changing the reflection,the transmission,and the attenuation of their transmission.The simulation results show that the plasma collision frequency,electron density,incident angle and magnetic field intensity have different effects on attenuation.The attenuation value increases at first then decreases when the collision frequency is simply increased.The increase of electron density increases the peak value of the attenuation.Attenuation value decreases with addition of external magnetic field.Thus the "blackout" problem can be effectively solved by applying constant external magnetic field.关键词
