Influences of EUT with different properties on the performances of a reverberation chamber

It is studied in detail that the influences of EUT with different properties on the reverberation chamber performances. Different amounts of absorbers have been added to load the chamber. It is found suitable amount of load may increase the chamber performance but more absorbers may decrease it. The influences of metal EUT on performance of a chamber have been studied by placing different size of metal enclosure in chamber. It is found a big size metal EUT deteriorate the performance though the load is small.
