Dynamic Range Improvement of Non Invasive Shielding Effectiveness Measurement Using a VIRC

This paper investigates the impact of the number of stirring configurations on shielding effectiveness measurements of shielded enclosures in different types of reverberation chambers, namely mode-stirred and vibrating intrinsic reverberation chambers. A non-invasive method based on Q-factor estimations is used to assess SE. Experimental results demonstrate that increasing the number of stirring configurations enhances measurement accuracy and enables the evaluation of higher SE values especially in vibrating intrinsic reverberation chamber.
