| 摘 要： | 强电磁脉冲能量通过小孔、缝隙等耦合到计算机机箱内,会对计算机产生干扰和破坏作用。本文应用时域有限差分法模拟了电磁脉冲对计算机机箱的耦合透入过程,通过分析机箱中电磁场和电磁能量随时间的变化曲线,得出了机箱中电磁脉冲的耦合变化特征。电磁脉冲对计算机机箱的耦合模拟计算可用于指导计算机系统的电磁兼容、干扰和防护研究。

| Abstract: | High power electromagnetic pulse couples into computer box through small apertures and slots, which can interfere with or destroy computer. The coupling process of electromagnetic pulse with computer box is simulated by using the finite-difference time-domain (FDTD) method. By analyzing the electromagnetic field and energy changing with time, the coupling characteristic of electromagnetic pulse is achieved. Besides, the simulation of electromagnetic pulse coupling with computer box is important for the research of electromagnetic compatibility, interference and defense of computer system. |
