Abstract

This paper analyzes the influence of simplifications in electromagnetic models used in the design of protections against High-Intensity Radiated Field (HIRF) threats. Both conductive and radiated effects are evaluated, covering the wide frequency range between 1 MHz and 6 GHz. A real and complex test case such as the power plant of an A400M aircraft was simulated using FDTD method so as to analyse the impact of different simplification approaches. The parameters studied are the inclusion/removal of installations, modification of electrical contacts, material properties, and changes in the cable features. In consequence, we can conclude that for the frequency range around tens or hundreds of megahertzs every detail is important (all the pieces of the model, accurate bundle routes and cable properties), while for higher frequencies only the details nearby the analyzed point are relevant for the results and it is not necessary to distinguish between different materials which are good conductors at this frequency range.
