Analysis of field probe perturbation in a mode stirred reverberation chamber

The residual stirring action of two commercially available electric field probes is experimentally and numerically analyzed. The capability to stir the reverberation chamber field is not negligible, and it alters the independent positions of mechanical rotating paddles when the spatial correlation matrix method is applied to evaluate them. The numerical code adopted for the simulations reveals its reliability and it can be employed to check probes during the design stage. Finally, we numerically evaluated the stirring effect of a conductor tripod that increases the independent positions.
