Reverberation chamber relationships: corrections and improvements or three wrongs can (almost) make a right

We correct a number of errors that have crept into the reverberation-chamber literature over the past several years. These include errors in equations and interpretation of data. Wherever possible, we identify the causes and implications of these errors. We pay particular attention to the so-called 4/spl pi//8/spl pi/ controversy where measurements appear to disagree with theory by approximately 3 dB. We also compare the power received by an antenna in an anechoic chamber and a reverberation chamber and give approximate equivalence relationships for comparison of such facilities.
