Abstract

The shielding performance of metallic enclosures at high frequencies is dominated by coupling through openings, especially long slots. In cases, where the size and shape of slots cannot be modified due to functional criteria, it may be possible to influence their position and orientation and the location of critical components inside the enclosure, and so to minimise the shielding degradation. In this paper, the influence of the slot position and source location, on the shielding performance of a metallic enclosure is investigated by means of numerical simulations. From the analysis results, general design guidelines are then developed
