Comparative analysis of electromagnetic field coupling to airborne cables in a reverberation chamber

In this paper , a comparative analysis of electromagnetic field coupling to airborne cables within a reverberation chamber is presented. The study focuses on assessing the electromagnetic field coupling to various cables in aircraft systems, which are critical for sustaining electronic functions such as power supply, data transmission, and communication between subsystems. Reverberation chambers have become integral for electromagnetic compatibility and over-the-air testing, offering a means to simulate complex electromagnetic fields. The full-wave Monte Carlo method is employed to accurately replicate the electromagnetic environment within a reverberation chamber. Through this simulation, the induced currents on different cable types illuminated by incident waves are evaluated. The findings reveal significant disparities in induced currents, with shielded twisted pair cables exhibiting the lowest induction currents and thus demonstrating the strongest resistance to electromagnetic interference. The presence of a shielding layer substantially reduces induces current intensity compared to unshielded wires, underscoring the effectiveness of shielding in mitigating electromagnetic interference. Statistical analysis of induced currents further validates the reliability of the Monte Carlo simulation method in replicating the reverberation chamber's electromagnetic environment. The pivotal role of cable in ensuring electromagnetic compatibility and resilience against external electromagnetic interference in aircraft systems is emphasized in this study.
