摘要
本文对于理想导体构成的屏蔽腔体，在开有小孔或者隙缝的情况下，用ＦＤＴＤ方法计算了屏蔽体外的强电磁脉冲对体内的影响，得到屏蔽体内的电磁场分布情况。计算结果表明，屏蔽体外强电磁脉冲对体内的影响主要局限于小孔附近。此结果对电子设备在强电磁脉冲下的防护有重要意义。
in this Paper,the FDTD method is applied to computing the electromagnetic field in a conducting box, which is excited by a powerful pulse coupled through a small hole on the box.The electromagnetic field distribution in the box is obtained.It shows that in the box,the influence of powerful electromagnetic pubs is mainly concentrated around the hole.The conclusion or significant to protect electric instrument from the powerful electromagnetic pnlse.
