临近空间中核爆源区电磁脉冲与等离子体流场耦合

Coupling of Source Region NEMP and Plasma Flow in Near Space

对临近空间中核爆源区电磁脉冲与飞行器等离子体流场的耦合进行了分析计算。对源区辐射场采用平面波近似和源区感应场直接计入等离子体电导率的影响,推导出新的差分迭代公式计算。计算结果可供临近空间飞行器电磁兼容性研究参考。

In this paper,the coupling of source region NEMP and plasma flow in near space is studied.To do this,the radiated fields in nuclear exploding source region is treated as plant wave,while the induced fields is calculated using a new iterative equation including the plasma effect.The results presented may be used in electromagnetic compatibility analysis of near space vihicles.
