Property of electromagnetic wave attenuation in the artificial plasmas of atmosphere
电磁波在大气层人造等离子体中的衰减特性

The electromagnetic property of the artificial plasmas of atmosphere was investigated with the Lorentz model.The effects of the frequency of electromagnetic wave,plasma density,and the electron-neutral collision frequency on the attenuation of electromagnetic wave were discussed.Numerical results indicate that the wave attenuation is stronger at the region of the longer wavelength and the higher plasma density.For the high plasma density,the wave attenuation is stronger at the lower electron temperature,and the higher altitude of atmosphere.
