Dual-factor coupling effect on electromagnetic susceptibility of airborne cables

Abstract

This paper investigates the eigenfrequency of the induced current in airborne cables to evaluate the coupling effect of dual-factor on electromagnetic susceptibility of airborne cables. The airborne cable is situated in the scaled fuselage which has lower complexity compared with the aircraft model. Based on the single-factor approach, the simulation results indicate that the electromagnetic environment and the fuselage have little effect on the eigenfrequencies. With the variations of cable length and cable height above the ground, the eigenfrequencies will change significantly. Based on the dual-factor of cable length and height, two improved analytical expressions for the eigenfrequency are proposed.
