Characteristics of HEMP Radiation Field on Typical Transport Aircraft with Frequency Sweep Method

Abstract

This paper presents characteristics of the HEMP radiation field on a typical transport aircraft using the frequency sweep method. Firstly, the characteristics of the HEMP field are analyzed. Then, various parameters including the electric field strength and magnetic field strength distribution are calculated using Altair FEKO software. Afterwards, the electric field strength distributions of three layers (top layer, inner layer and bottom layer) are calculated and analyzed. The results indicate that the HEMP induced field is affected by the aircraft body. The induced electric field strength E(t) varies greatly at different positions. Nevertheless, the peak value of E(t) is usually greater than the initial peak value of electric field strength E0. Such a study can provide guidance and insight into the protection design of the HEMP of the aircraft.

“…Considering the importance and vulnerability of airborne equipment, high-altitude electromagnetic pulse (HEMP) protection of airborne equipment is necessary. In this context, Hu et al in [12] studied the characteristics of the HEMP radiation field on a typical transport aircraft using the frequency sweep method. The authors typically calculated and analyzed the electric field strength distributions of three layers (top, inner, and bottom layers).…”
