Fabrics SE measurements in a Reverberation Chamber by an apertured TEM cell and by a small nested Reverberation Chamber

In this paper the Authors compare three methods to perform Shielding Effectiveness measurements on shielding materials: the Dual Tem Cell method, the apertured TEM cell in Reverberation Chamber (RC) method and the nested RCs method. The aim of the work is to compare the experimental results of the different measurement systems on the same samples of cotton canvas. The criteria adopted to make the comparison are briefly explained and the results achieved are presented. Moreover, the possibility that the tests performed using the nested RCs are “Near Field measurements” are discussed.
