摘要

采用矩量法对气流阵列中孔径或缝隙之间的耦合进行了数值研究。应用于屏蔽外壳设计是特别感兴趣的。给出了先前提取的一种简单的经验设计方法，证明了孔径数N和尺寸a与气流孔径阵列的屏蔽效能/spl sim/Na/sup 3/之间的关系。研究了槽间的耦合。论证了经验设计方法的应用局限性。

Slot and aperture coupling for airflow aperture arrays in shielding enclosure designs

The coupling between apertures or slots in airflow arrays is investigated numerically by means of the method of moments (MoM). Application to shielding enclosure design is of particular interest. Justification for a previously extracted simple empirical design approach for the relation between the number N and size a of apertures, and the shielding effectiveness /spl sim/Na/sup 3/ for an airflow aperture array is given. The coupling between slots is also investigated. The application limit of the empirical design approach is demonstrated.
