The detonation of a nuclear weapon at high altitude has long been known to generate an intense short burst of electromagnetic radiation, referred to as an Electromagnetic Pulse (EMP). This pulse has the potential to cause considerable harm to electrical power systems, as well as other essential infrastructure sectors. The effects of an EMP on the power grid are heavily dependent on the three-dimensional distribution of the rocks beneath our feet. Additionally, components that are vulnerable to destruction by sudden pulses of electromagnetic energy should be eliminated.
Chinese researchers have urged their government to increase the country's readiness to protect itself against a high-altitude EMP attack. To do this, two main types of large simulators are used: metal structures that guide an electromagnetic wave past a test object, and antennas that radiate an electromagnetic field to the object. The ionized deposit ion region (source) is stimulated to emit much of its energy in the form of an electromagnetic pulse in the radio frequency spectrum. If the symmetry of the ionized sphere is altered, non-radial oscillations will begin and energy will be emitted in the form of a pulse of electromagnetic radiation, much of which is in the radio frequency region of the spectrum.
In general, components such as capacitors, transistors, and diodes are listed in order of decreasing susceptibility to damage caused by a sudden pulse of electromagnetic energy. It is important to note that these components should be removed in order to reduce the risk of damage caused by an EMP.
