High-Altitude Electromagnetic Pulse (HEMP) and IEMI (Intentional Electromagnetic Interference) are two special electromagnetic threat/mitigation scenarios. A HEMP is the result of a nuclear detonation at an altitude greater than 30 miles. The electromagnetic field generated by the effects of gamma rays interacting with the atmosphere at approximately 15-30 miles in altitude is what is referred to as an “Electromagnetic Pulse”. Such a pulse can be very intense (50,000 V/m) and very broadband, subjecting a variety of electronics and power and other infrastructure to potential damage.
Many military systems have already been hardened for EMP through design or the creation of special shielded environments suitable for military operations. However, Civil Infrastructure is still very vulnerable to damage from an EMP.
Mitigation of EMP effects is a complex undertaking, and the specific actions taken will depend upon equipment or facility criticality, size, geographic span, and interconnections.
Military systems are often enclosed in a fully-shielded environment composed of a highly conductive material (often steel) with penetrations specially designed to accommodate function with RF shielding.
This is generally not an approach that fits most Civil Infrastructure. For instance, a power system includes generation stations, transmission lines, substations, and distribution infrastructure. There is no sensible way to completely shield such a geographically dispersed system. Mitigation of such a complex system must utilize measures such as logistical spares, redundancy, and critical subsystem hardening to minimize damage and downtime to the overall system functionality.
FMS provides EMP consultation services around the world to assist in mitigating the increasing threat of EMP and IEMI to civil infrastructure around the world.
Our services include:
FMS has extensive experience with all aspects of electromagnetic protection from the impact of EMP/IEMI threats. FMS’ staff have experience developing unique mitigation approaches and have collaborated closely with experts and clients around the globe in the design and implementation of civil infrastructure resilience that matches the electromagnetic threats that are likely to be encountered. FMS staff have “written the book” on EMP hardening measures for civil infrastructure in collaboration with experts around the world.
