Theoretical Radiated Emission Prediction of an Aperture Array by Reverberation Chamber Field Sampling

This paper reports the application of a theoretical model designed to predict the electromagnetic field radiated by a piece of equipment under test through an array of apertures on its metallic chassis. The simulated scenario is a reverberation chamber where the electric field is measured close to its walls. At this scope the multipole monopole source stirring technique is considered because of the presence of the antennas onto the chamber's walls. The results are successfully compared to the emissions in free space, and a wideband frequency analysis is performed. Finally, the effect of a random numeric noise on the module and on the phase of the electric field samples is analyzed.
