An electromagnetic pulse (often shortened to EM pulse) is a natural or artificial burst of electromagnetic energy.
In 1995, the Soviet Union developed a weapon capable of firing a controlled electromagnetic pulse. (TNG novel: Ghost Ship)
In late 2373, the USS Enterprise-E was continually swept by high-density EM pulses during a battle with two Cardassian Galor-class warships.
