We live in a modern world powered by large, complex systems, including financial markets, communication networks, transportation networks, and security infrastructure. Sensitive electronics are omnipresent, making them increasingly vulnerable to high-power electromagnetic (HPEM) threats - an emerging risk capable of disrupting critical networks and the infrastructure they support. This book explores recent advances in HPEM sources, electromagnetic compatibility (EMC), strategies for protecting against intentional electromagnetic interference (IEMI) and detection and mitigation of these threats.

This book is an edited selection of invited papers that have been updated and expanded from the 2022 GlobalEM Conference. It offers an in-depth overview of the state of the art in high-power electromagnetics, including high-power microwave and ultrawideband sources, intentional electromagnetic interference, electromagnetic compatibility, and detection methods for IEMI threats.

The book will help readers working in high-power electromagnetics and related fields to:

• Understand the capabilities of modern HPEM sources;
• Understand the threats represented by HPEM on modern critical infrastructures, systems, and equipment;
• Identify the coupling mechanisms of different HPEM sources in different scenarios;
• Identify the efficacy of shielding, filtering, hardening and other protection mechanisms.
