Abstract: The field uniformity of the same reverberation chamber is validated by the traditional method which is based on maximal field, and its results indicate that the technical specification of reverberation chamber is much better than that required in related international standard. A new method based on the probability distribution of field is introduced here. The field during the whole period of stirrers' rotating is taken into account. The general accordance from these two methods indicates that the new method is useful for the validation from another new point of view. The partial difference proves that the new method should be adopted for better specification supporting in some special applying, such as maximum reading distance measurement for radio frequency identification and simulation of complex wireless channel.
