Approche mixte théorie / expérimentation pour la modélisation numérique de chambres réverbérantes à brassage de modes

Abstract : This Ph.D thesis deals with computing a full methodology to simulate the behaviour of Mode Stirred Reverberation Chambers (MSRCs). With this test facility, immunity and susceptibility experiments for electronic devices may be achieved in the domain of electromagnetic compatibility (EMC). The aim of these works is to propose a numerical modelling of MSRC which takes into account as many real characteristics as possible. The FDTD method is used to solve Maxwell's equations. The geometrical characteristics of MSRC devices are applied in the numerical domain with the help of digital geometry ; it enables to control the topologic properties of tridimensional meshes. The intrinsic characteristics (MSRC losses) are integrated in a post treatment process involving a specific filter. The influence of the source on the numerical incident power is carefully detailled. Eventually, these works end with a comparison between numerical and experimental results based upon normative and statistic criteria.
