Influence of different-shaped apertures on the HIRF coupling

摘要

For the needs of routing and ventilation, the enclosures of electric equipments are always with a lot of aperture. Although the sizes of these apertures are very small, electromagnetic field can be coupled in the shield while the frequency of the incident wave is relatively higher. The electromagnetic simulating software FEKO is used to analysis the influence on HIRF coupling brought by different-shaped apertures.
