http://ece-research.unm.edu/summa/notes/SSN/SSN573.pdf An EMP arises where the source emits a short-duration pulse of energy. The energy is usually broadband by nature, although it often excites a relatively narrow-band damped sine wave response in the surrounding environment. Some types are generated as repetitive and regular pulse trains. Different types of EMP arise from natural, man-made, and weapons effects.

HEMP is caused by a nuclear burst at high altitudes. Prompt gamma rays following the nuclear detonation are the principal source of HEMP. This gamma radiation causes bursts of electron flow from the Compton effect, a photoelectric effect, and a “pair production” effect. Of these three effects, however, the primary source of HEMP is … how many tasks to luminous in adopt me

高高度核爆発 - Wikipedia

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 specific characteristics of a particular nuclear EMP event vary according to a number of factors, the most important of which is the altitude of the detonation. WebDecember 2013. EPRI White paper provides background and an introduction to electromanetic pulse (EMP), high altitude EMP (HEMP) and intentional electromaagnetic interference (IEMI). This is the first in a series of EPRI papers and reports to address the impacts and mitigration stratgies.
