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.
