An energy analysis of the EMP damped sinusoid

Abstract

The susceptibility of a circuit to damage from an electromagnetic pulse (EMP) such as lightning or nuclear EMP is often tested by driving the circuit with an exponentially damped sine wave. The energy content of this function is derived in the time and frequency domains for both resistive and resonant loads, leading to a method of specifying the cutoff frequency of lowpass filters so as to limit the energy transferred from an EMP or EMP simulator to a specified burnout level.<>
