Research Overview
Background: The detonation of a nuclear weapon at high altitude or in space (~30 km or more above the earth’s surface) can generate an intense electromagnetic pulse (EMP) referred to as a high-altitude EMP or HEMP. HEMP can propagate to the earth and impact various ground-based technological systems such as the electric power grid. Depending on the height of the explosion above the earth’s surface and the yield of the weapon, the resulting HEMP can be characterized by three haz
