On The Use Of Fdtd For Hirf Validation And Certification

Preparing the 3D-geometry models to perform electromagnetic compatibility (EMC) numerical simulations can be tedious and time consuming. Furthermore, the need to include the test setup in the models, in order to validate the software, by comparing the numerical results with the measured data, may lead to unwieldy simulation models with often unaffordable computational costs. In this paper, we illustrate a procedure to optimize and simplify the modeling process, together with guidelines for achieving the most unfavorable case in the simulation of EMC problems, as required for a certification process. A test case from the European FP7 HIRF-SE (High-Intensity Radiated Field Synthetic Environment) project is analyzed in this paper as an example of how to identify the unnecessary elements for the simulation, while retaining the essential physics of the problem.
