Beschreibung
Electrical and electronic systems can be found in almost all areas of public and private life. In many cases, they also form essential components of critical infrastructures (KRITIS). Critical infrastructure systems in particular must function extremely reliably and safely, as a partial or even complete failure can lead to far-reaching physical, material or financial consequences. Radiated electromagnetic environments, which can adversely affect circuits and systems, pose a significant risk. While classical EMC tests (electromagnetic compatibility) typically verify immunity to electromagnetic environments with field strengths of a few V/m, so-called HPEM environments (high-power electromagnetics) are not usually considered. By definition, however, these have field strengths of more than 100 V/m and can therefore deliberately cause interference or even destruction.
In this paper, the intended effects of various HPEM environments, including the High-Altitude Electromagnetic Pulse (HEMP), are analysed by means of a transient immunity analysis in order to identify and demonstrate the main differences in electromagnetic effects using a real system as an example. To this end, the real system is broken down into its components using electromagnetic topology (EMT) in order to analyse the coupling of HPEM environments.
