  2. Electromagnetic pulse - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_pulse

    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.

  3. Electromagnetic shielding - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_shielding

    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.

    The EMP damage of the Starfish Prime test was quickly repaired due, in part, to the fact that the EMP over Hawaii was relatively weak compared to what could be produced with a more intense pulse, and in part due to the relative ruggedness (compared to today) [10] of Hawaii's electrical and electronic infrastructure in 1962. [11]

  6. Electromagnetic absorption by water - Wikipedia

    Water vapor concentration for this gas mixture is 0.4%. Water vapor is a greenhouse gas in the Earth's atmosphere, responsible for 70% of the known absorption of incoming sunlight, particularly in the infrared region, and about 60% of the atmospheric absorption of thermal radiation by the Earth known as the greenhouse effect.

  9. Electron precipitation - Wikipedia

    en.wikipedia.org/wiki/Electron_precipitation

    In order to cause electron precipitation, transmitters must produce very powerful waves with wavelengths from 10 to 100 km. [3] Naval communication arrays often cause transmitter-induced precipitation of electron radiation (TIPER) because powerful waves are needed to communicate through water. These powerful transmitters are operating at almost ...
