Some Consideration on Shielding Effectiveness Testing by means of the Nested Reverberation Chambers
MetadataShow full item record
This paper evaluates the effects of test fixture isolation when using nested mode-stir chambers for conducting electromagnetic shielding measurements. The nested chamber technique is used by both government and industry to evaluate the electromagnetic attenuating properties of materials as varied as infrared sensor windows to the composites used in the hulls of new ships, EM-protection of human as well as devices. Numerical simulation by means of CST and FEKO software of different nested chambers arrangements were done. Some preliminary test measurements of designed and manufactured the small reverberation chamber were done and compare with the numerical simulation results.
