A conductive enclosure used to block electrostatic fields is also known as a Faraday cage. The amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of holes in a shield to an incident electromagnetic field.
Faraday cages cannot block stable or slowly varying magnetic fields, such as the Earth's magnetic field (a compass will still work inside one). To a large degree, however, they shield the interior from external electromagnetic radiation if the conductor is thick enough and any holes are significantly smaller than the wavelength of the radiation.
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 .
In 2018, the US Department of Homeland Security released the Strategy for Protecting and Preparing the Homeland against Threats from Electromagnetic Pulse (EMP) and Geomagnetic Disturbance (GMD), which was the department's first articulation of a holistic, long-term, partnership-based approach to protecting critical infrastructure and preparing ...
Iran does have a nuclear program, and probably could build a nuclear EMP weapon if it wanted to. The 2015 nuclear deal Iran's nuclear weapons program in return for lifted sanctions. But the Trump ...
TEMPEST is a codename, not an acronym under the U.S. National Security Agency specification and a NATO certification [1] [2] referring to spying on information systems through leaking emanations, including unintentional radio or electrical signals, sounds, and vibrations.
