Coupling effect analysis of airborne cable under high intensity radiation field environment

With the improvement of equipment informatization, the importance of electromagnetic compatibility and the adaptability of complex electromagnetic environment has become increasingly prominent, and the influence of high intensity radiation fields (HIRF) on aircraft electronic equipment has become more and more significant, which has seriously threatened flight safety. In order to examine the coupling characteristics of airborne cables under HIRF irradiation, this paper used FEKO electromagnetic simulation software for analyse and study. The influence of different radiation fields, cable types, installed positions and gap structure on the simulation results was analyzed. And coupling patterns of airborne cables in the HIRF environment were obtained. The conclusions obtained in this paper have a definite guiding significance of the research on airborne cable protection for HIRF.
