| Abstract: | Using the model of multi-photon nonlinear Compton scattering, the influences on attenuation characteristics of electromagnetism wave in plasma by Compton scattering is studied. It is advanced that Compton scattering is an important influence mechanism on the attenuation characteristics of electromagnetism wave in plasma, and the formulas on attenuations of the electromagnetism wave energy and power are derived and simulated numerically. The results show that Compton scattering can take bigger influences on the attenuation of electromagnetism wave in plasma, and the results between the theory computation and numerical simulation are very coincident. The results can give the theory basis for deciding the Compton scattering taking place in the plasma. |
