Numerical simulation of a Reverberation Chamber with a stochastic collocation method

An original numerical modelling of Mode Stirred Reverberation Chamber used in Electromagnetic Compatibility is proposed. This method relies on an analogy between a reverberation chamber and an enclosure whose wallsʹ conductivity is randomly characterised. The distribution law of this parameter is obtained by measurements. Applying a stochastic collocation method enables one to numerically assess electromagnetic field from a low number of empty cavity (without stirrer) simulations. Thus this approach notably reduces CPU time allowing more complex simulations. To cite this article: P. Bonnet et al., C. R. Physique 10 (2009).
