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 and damage electronic equipment. An EMP such as a lightning strike can physically damage objects such as buildings and aircraft. The management of EMP effects is a branch of electromagnetic compatibility (EMC) engineering.
The first recorded damage from an electromagnetic pulse came with the solar storm of August 1859, or the Carrington Event.[1]
In modern warfare, weapons delivering a high energy EMP pulse are designed to disrupt[2] communications equipment, the computers needed to operate modern warplanes, or even put the entire electrical network of a target country out of commission.[3]
