系统电磁脉冲空间电荷层振荡特性理论

Oscillation characteristic of space charge boundary layer of SGEMP

从电磁场理论出发,给出了发射电子为单能条件下系统电磁脉冲(SGEMP)空间电荷层振荡特性的解析求解方法,得到了空间电荷层的振荡频率和振荡幅度的解析式,其结果与用等离子体理论求解得到的结果一致。通过本文的研究工作,可以进一步认识发射电子为单能条件下SGEMP中的空间电荷层问题,该问题可以分别用电磁场理论和等离子体理论处理。

The oscillation characteristics of space charge boundary layer of the System Generated Electromagnetic Pulse（SGEMP） are studied based on electromagnetic theory with the emitted electron being monoenergetic. The analytical formula of frequency and amplitude are obtained, which accord with the results by plasma theory. Then the issue that the space charge boundary layer does exist when emitted electron is monoenergetic has been further understood, which can be addressed with both the electromagnetic theory and the plasma theory.
