Description
Summary:In the field of vulnerability to intentional electro-magnetic interference (IEMI), relevant coupling mechanism into complex electronic systems must be investigated. Thereby the estimation of the coupled disturbances into the systems is of special interest. This paper presents a detailed method, which allows an estimation of the vulnerability of complex systems to electromagnetic attacks. It is based on the characterisation of external interfering sources and it characterises the system by segmenting it into subproblems with respect to the different coupling mechanisms. Then the obtained subproblems are solved with the electromagnetic topology (EMT), and finally they are superposed to the overall solution. This procedure allows the identification of the critical coupling paths of the investigated system. Afterwards a specific implementation of different solutions for electromagnetic hardening is possible.
