Abstract

Abstract

The feasibility of mode stirred reverberation chambers(MSRCs) constructed by using flexible shielding materials is investigated, whose uneven walls enable them easily meet the requirements of the statistic characteristics of isotropic, uniform distribution and random polarization. The field uniformity and the probability density function(PDF) of normalized electric field are measured, and the results are in accordance with the standard IEC 61000-4-21-2011 and the PDF of ideal MSRC model. Then the influence of the stirrer rotation speed, antenna height and position on PDF of normalized electric field is analyzed experimentally. Finally, the flexible shielding material based reverberation chamber is used to measure the shielding effectiveness(SE) of an electrically large cavity with and without water load, demonstrating a good feasibility.
