为了研究Compton散射对等离子体球太赫兹(THz)散射特性的影响,将多光子非线性Compton散射模型引入到该研究中,提出了将Compton散射作为影响等离子体球太赫兹散射的重要因素,给出了各向异性等离子体球散射场修正方程及介电常数张量、观测方位、极化状态等因素对THz波散射的影响,并进行了仿真实验。结果表明:微分散射截面随THz波频率变化近乎呈准谐振规律变化,较散射前增大了0.001;微分散射截面随观测方位和极化状态的变化较散射前增大了0.002。
In order to study the effect of Compton scattering on the THz scattering characteristics of the plasma sphere, a multi-photon nonlinear Compton scattering model is introduced into this study. It is proposed that Compton scattering be used as an important factor affecting the terahertz scattering of the plasma sphere, The anisotropic plasma ball scattering field correction equation and the dielectric constant tensor, observation azimuth, polarization state and other factors on the THz wave scattering, and the simulation experiment. The results show that the differential scattering cross section changes almost quasi-resonantly with the frequency of THz wave and increases by 0.001 before scattering. The variation of differential scattering cross section with observation azimuth and polarization state increases by 0.002 compared with that before scattering.
