Sophisticated electronic technologies are increasingly used in mission- and safety-critical systems where electromagnetic interference (EMI) can result in substantial risks to people and the environment. Currently, EMI engineering follows a rule-based approach, which is unable to cope with complex modern situations. With this rules-based approach, during the design stage, guidelines are used, which result in the application of a set of mitigation techniques, which are verified in the finished product against standards. This rulebased approach is costly, but with no guarantee of the required performance. This is particularly so for sensitive medical applications or the fully autonomous systems that are becoming ever-more common in our society. What we need is a risk-based approach, which is what PETER1, the Pan-European Training, Research & Education Network on Electromagnetic Risk Management, will provide. PETER is training 15 young engineers in topics related to the development of high-tech systems that maintain reliability and safety over their full lifecycle, despite complex EMI, such as in hospitals or transport systems. This is achieved using best practices and state-of-the-art EM engineering, reliability engineering, functional safety, risk management and system engineering, to create the riskbased EMC approach.
