核电磁脉冲模拟器的电场特性及等离子体阵列的防护性能

强电磁脉冲通过电子设备表面耦合进入内部将产生显著的破坏作用，而等离子体作为一种特殊的电磁介质，具有屏蔽强电磁脉冲的能力，因此基于等离子体的强电磁脉冲防护研究具有重要意义。利用CST软件仿真分析了核电磁脉冲模拟器工作空间的电场分布。进行了核电磁脉冲对单片机的干扰和破坏效应辐照研究，得到了其对MF-51-1型单片机的干扰和破坏阈值分别在10 kV/m和18 kV/m左右。实验研究了单层等离子体阵列对核电磁脉冲的防护性能，能量衰减均在10 dB以上。实验结果表明，等离子体具有强电磁脉冲防护的能力。
Strong electromagnetic pulse may cause serious damage once it is coupled into the interior of the electronic system. As a kind of special electromagnetic medium, the plasma has the ability of shielding strong electromagnetic pulse. Therefore, electromagnetic pulse protection technology based on the plasma is of practical significance. The electric field distribution in work space of the nuclear electromagnetic pulse simulator was simulated and analyzed by the CST software. The interfering and damaging effect of the single chip microcomputer under irradiation of the nuclear electromagnetic pulse was studied, the results showing that the interfering and damaging thresholds of the nuclear electromagnetic pulse to MF-51-1 MCU are 10 kV/m and 18 kV/m respectively. The protection performance of the one layer plasma array to the nuclear electromagnetic pulse was experimentally studied, and the energy attenuation value can reach up to 10 dB. The research results show that the plasma has the protection ability against strong electromagnetic pulse.
