The Research on Frequency-Domain Characteristics of Electromagnetic Pulse

Abstract

In this paper, Frequency-Domain characteristics of three different sets of High-altitude electromagnetic pulse (HEMP) are calculated by Fourier transform. Results prove that the frequency spectrum characteristics, normalization cumulative power energy and power energy spectrum density are relationship with the HEMP waveform parameter. It is possible to be helpful to the HEMP coupling research and the HEMP protection techniques research. Furthermore, the result can be used to expand HEMP generator application in the civil system by changing HEMP waveform parameters. It is possible to use the results to model high-power electromagnetic devices that is non-standard and has short pulse duration.
