Vibrating Intrinsic Reverberation Chambers for shielding effectiveness measurements

A new technique for shielding effectiveness measurements is the dual VIRC method. In this method two Vibrating Intrinsic Reverberation Chambers (VIRC) are combined together via a common wall with an aperture that forms the interface between them. This particular set-up makes it possible to achieve a very high dynamic range. Advantage of this technique compared to the nested reverberation set-up is that measurements can be conducted much faster and at much lower frequency. Several different approaches to determine the shielding effectiveness are presented. It has been shown that multiple interactions play a role in the particular set-up.
