摘要
研究束-等离子体系统中不稳定静电波转变成频率为ω_p的电磁辐射的参量衰变过程。利用Zakharov方程导出了参量衰变色散关系,并由此得到了束-等离子体系统的辐射率。利用该辐射率计算出的辐射功率与实验结果符合得很好。
The process of parametric decay by which unstable electrostatic waves are converted into electromagnetic radiation with frequency ω_p is investigated. The dispersion relation of parametric decay is derived from Zakharov's equation. From this, the radiation rates of beam-plasma system are also obtained. The numerical calculation results using this radiation rates are accorded with experiment well.
