屏蔽室接地位置不同对其屏蔽效能的影响研究
Influence of grounding locations on shielding effectiveness of shielded room
摘要
Abstract
In order to analyze the influence of grounding locations on the shielding effectiveness （SE） of shielded room, numerical simulation is done by applying par-allel time-domain finite-difference （FDTD） method on the coupling problems between shielded room and two high power electromagnetic environments, that arelightning electromagnetic pulse （LEMP） and altitude electromagnetic pulse （HEMP）, respectively. Inner coupled electromagnetic （EM） fields are calculatedwhen the shielded room is with different grounding locations. The results indicate that the farther the distance between the grounding location and the aperture, the better the SE of shielded room.关键词
