A global approach to time-domain shielding problems

Abstract

The local and frequency-domain approach to shielding performance analysis of classical IEEE Std. 299 may be not sufficient for the thorough appraisal of protection levels achievable through actual enclosures in the presence of transient electromagnetic fields. Stemming from a victim point of view, a new, global approach is proposed for the assessment of average and minimum guaranteed shielding performance directly in the time domain. The method is suitable and recommended for the analysis of protection levels of mission-critical devices or systems.
