Abstract :
Two setups for shielding effectiveness measurements of conducting textiles were examined. The first setup was based on IEEE Standard 299 method applied for an anechoic chamber. The second setup was arranged in dual Vibrating Intrinsic Reverberation Chamber. In both setups resonance modes are unavoidable. In the first one they deteriorate final results, while in the second one they improve dynamic range. The second method has the great advantage: oblique incident wave at arbitrary polarizations giving realistic ambient for measurements. A few examples of measurement results are given to illustrate predominancy of the dual VIRC approach over IEEE Std 299 based method.
