摘要
应用时域有限差分法 ,研究了屏蔽机箱上贯通导线对机箱内电路HEMP耦合电流的影响。研究表明 ,贯通导线通过与入射场及屏蔽机箱的散射场耦合 ,可使机箱内与贯通导线直接相连或不相连电路上的HEMP耦合电流显著增强。此研究对电台、微机等电子设备和系统的核电磁脉冲防护具有十分重要的意义。
In this paper, effects to HEMP induced current in circuits inside the shielding box caused by penetrative wire were studied. Results show that penetrative wire can make HEMP induced current in circuits inside the shielding box increase greatly through coupling with incident field and scattering field of the shielding box. The work done here is useful to estimate the HEMP coupling to electronic apparatus and systems such as radio and computer.
