An electromagnetic pulse ( EMP ), also referred to as a transient electromagnetic disturbance ( TED ), is a brief burst of electromagnetic energy. The origin of an EMP can be natural or artificial, and can occur as an electromagnetic field, as an electric field, as a magnetic field, or as a conducted electric current. The electromagnetic interference caused by an EMP can disrupt communications ...
ATLAS-I was the largest NNEMP (non-nuclear electromagnetic pulse) generator in the world, designed to test the radiation hardening of strategic aircraft systems against EMP pulses from nuclear warfare. Built at a cost of $60 million, it was composed of two parts: a pair of powerful Marx generators capable of simulating the electromagnetic pulse ...
High-altitude nuclear explosions are the result of nuclear weapons testing within the upper layers of the Earth's atmosphere and in outer space. Several such tests were performed at high altitudes by the United States and the Soviet Union between 1958 and 1962.
Nuclear electromagnetic pulse. 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.
Electromagnetic shielding is the process of lowering the electromagnetic field in an area by barricading it with conductive or magnetic material. Copper is used for radio frequency (RF) shielding because it absorbs radio and other electromagnetic waves. Properly designed and constructed RF shielding enclosures satisfy most RF shielding needs ...
EMP Merchandising, also known as Large Popmerchandising (in the Netherlands and Belgium), is a German-based music mail order and merchandising store. The abbreviation EMP stands for Exclusive Merchandise Products.
An electron microprobe (EMP), also known as an electron probe microanalyzer (EPMA) or electron micro probe analyzer (EMPA), is an analytical tool used to non-destructively determine the chemical composition of small volumes of solid materials. It works similarly to a scanning electron microscope: the sample is bombarded with an electron beam ...
