This work presents a selection of contributions presented at the GlobalEM 2022 Conference supplemented by a selection of unpublished studies from key experts from the high-power electromagnetics (HPEM) community. It provides a discussion on the state-of-the-art in high-power electromagnetics (HPE) technologies, focusing on high-power microwave and ultrawideband sources, intentional electromagnetic interference (IEMI), electromagnetic compatibility (EMC), and detection methods for IEMI threats.
