In this article, a UAV demonstrator (DEMO-E3) with different test cases is evaluated through the low-level swept field test following a nested resonant chambers approach, which is framed under the high intensity radio frequency measurements. The aim is to analyze the difference in terms of the shielding effectiveness of the enclosure considering the different materials and apertures of each test sample. Some of the test cases had been previously measured independently, according to the IEC 61000-4-21 standard, while in this study, they are incorporated into the demonstrator and former results are used as a comparison.engComposite materialshigh intensity radiated field (HIRF)low-level swept field (LLSF)shielding effectiveness (SE)info:eu-repo/semantics/article10.1109/TEMC.2022.32026361558-187Xinfo:eu-repo/semantics/restrictedAccess
