Abstract :
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 ~Na3 for an airflow aperture array is given. The coupling between slots is also investigated. The application limit of the empirical design approach is demonstrated
