On the response and immunity of electric power infrastructures against IEMI — Current Swedish initiatives

IEMI is not a new research topic especially for military applications. However, not much attention has been paid in the past to the possibility that this type of threat could be used against civilian critical infrastructure by terrorist groups or other rough elements. Moreover, just a few research programs, mainly conducted in the U.S., have been reported combining power systems and high altitude nuclear high-altitude electromagnetic (HEMP) pulse. The present manuscript is aimed to present various Swedish research activities planned to provide the necessary knowledge to improve the electromagnetic requirements/susceptibility level against IEMI threats of future digital and electronic components used on different critical infrastructures system.
