Abstract

This paper presents a novel hybrid nested

reverberation chamber measurement technique for

shielding effectiveness measurement of the conductive

fabrics. The test setup consists of a conventional outer

reverberation chamber and a small inner chamber whose

walls and ceiling are covered with electromagnetic

absorbers. Therefore, the inner chamber acts as a semi-

anechoic chamber, whereas the outer chamber acts as a

reverberation chamber (RC) and the proposed test setup

shows a hybrid characteristic. In this study, firstly, the

field uniformity of the outer RC is experimentally verified

considering the IEC 61000-4-21 standard in the frequency

range of 2-10 GHz. Afterwards, both the shielding

effectiveness of the conductive fabric and the dynamic

range of the proposed nested reverberation chamber

(NRC) technique are obtained. Moreover, the obtained

results are compared with the MIL-DTL-83528G test

method.
