A nuclear electromagnetic pulse (nuclear EMP or NEMP) is a burst of electromagnetic radiation created by a nuclear explosion. The resulting rapidly varying electric and magnetic fields may couple with electrical and electronic systems to produce damaging current and voltage surges.

The detonation of a nuclear weapon at high altitude or in space can generate an electromagnetic pulse (EMP), referred to as a high-altitude EMP (HEMP), that consists of three components: E1, E2, and E3.

A high-altitude electromagnetic pulse (HEMP) weapon is a NEMP warhead designed to be detonated far above the Earth's surface. The explosion releases a blast of gamma rays into the mid- stratosphere, which ionizes as a secondary effect and the resultant energetic free electrons interact with the Earth's magnetic field to produce a much stronger ...

2008年7月21日 · High-Altitude Electromagnetic Pulse (HEMP) is a near-instantaneous electromagnetic energy field that is produced in the atmosphere by the power and radiation of a nuclear explosion, and that is damaging to electronic equipment over a very wide area, depending on power of the nuclear device and altitude of the burst.

2024年7月17日 · The People’s Republic of China (PRC) possesses high-altitude electromagnetic pulse (HEMP) weapons designed to paralyze electronic infrastructure–such as telecommunications and industrial control systems.

2024年12月6日 · The high-altitude electromagnetic pulse (HEMP) generated by nuclear explosions in the outer atmosphere is a significant threat to electric power and information system because of its wide coverage (Explosion radius is of the order of 10 3 km), high peak intensity, and many destructive targets.

Three main phenomena take place in the wake of a high-altitude nuclear burst. First, the interaction between gamma rays and atmospheric air molecules produces a prompt EMP field, also referred to as E1. This EMP peaks at tens of kilovolts per meter in a few nanoseconds and lasts for a few hundred nanoseconds.

2024年7月1日 · An electromagnetic pulse (EMP) is defined as a high amplitude, short duration, broadband pulse of electromagnetic energy that can have devastating effects on unprotected electronic equipment and systems. EMPs are historically known as the electromagnetic effects following a nuclear blast occurring at high altitudes. The Science Behind EMP

Electromagnetic Pulse EMP is an instantaneous, intense energy field that can overload or disrupt at a distance numerous electrical systems and high technology microcircuits, which are especially sensitive to power surges. A large scale EMP effect can be produced by a single nuclear explosion detonated high in the atmosphere.
