摘要在电子设备飞速发展的今天,电磁干扰随之产生。在设备上为了通风散热所开的孔缝,不可避免会导致设备受到外部的电磁干扰。因此研究孔缝耦合对屏蔽效应的影响十分重要。本文在国内外研究现状和电磁学理论的基础上 ,对孔缝耦合如何影响屏蔽效能进行了探究。利用CST软件建模仿真,探究了对于孔缝的不同形状对屏蔽效应的影响、对于不同的孔缝面积如何影响屏蔽效能、对于入射波入射方向及频率对屏蔽效应的影响、矩形体壁厚对屏蔽效应的影响以及多个孔缝如何影响屏蔽效应,从而得出普遍意义的结论。21780

Title Coupling Apertures Make a Difference in Electromagnetic Shielding
Abstract
Today,the electronic device is development rapidly, electromagnetic interference is produced. On the equipment, it is opened some apertures for ventilation. Electromagnetic interference is influence the equipment. Therefore, it is important to research the coupling apertures how to impact the shielding. This paper is based on the electromagnetic theory to explore how to influence the shielding effectiveness coupling apertures. Use the CST software, to explore the different shapes of the apertures how to effect, for different apertures area how to affect the shielding effectiveness, for the different of direction and frequency of the incident wave how to impact on the shielding, the impact of the wall thickness of the shielding effect and how about the some apertures to effect the shielding. In the end, we get the conclusion.
