摘要
孔缝电磁耦合是外部电磁环境对飞行器的重要作用途径,建立与之相关的分析模型,有助于提高其环境适应能力;以平板孔缝耦合为典型对象,首先建立了无限大平板的小孔耦合模型,然后利用矩量法对孔缝耦合模型进行求解分析,得到了表征电磁耦合强弱的能量传输系数;为验证方法的有效性,搭建实验系统对不同的孔缝类型进行了测试,结果表明,在电磁波垂直入射情况下,矩形和圆形孔缝的电磁能量传输系数具有较好的一致性。
The aperture coupling of electromagnetic wave is the main coupling path into aircraft, here EMC model relative to it is, which is helpful to improve system electromagnetic compatibility. In this paper, firstly, in terms of the Moment Method （MoM）, the electromagnetic coupling through a small aperture on conducting surfaces is analyzed. The EM energy transmission coefficient through the aperture on conducting surfaces is calculated. Several coupling models are built to validate its effectiveness; the experimental and analyzed results are shown in good agreement with each other.
