Study on Electromagnetic Pulse Effect of Complex Electronic Systems

With the development of large scale integrated circuits,electronic devices become increasingly miniaturized and complex in structure.The tolerance of complex electronic systems against electromagnetic pulse becomes lower and lower,which may easily result in performance degradation,damage or even explosion of system under electromagnetic pulse interference.Considering the destructive effects of electromagnetic pulse,high-altitude electromagnetic pulse(HEMP) is taken into account.The characteristics of electromagnetic pulse and the numerical methods for studying electromagnetic pulse effect are analyzed,then the aperture coupling process of double-layer metal cavities under HEMP plane wave is simulated using FDTD.The conclusions provide a guidance for the protection design of metal cavities.
