Kurtosis index to characterise near line-of-sight conditions in reverberating chambers

In this study, the kurtosis index, k, is first applied to the phase of the electromagnetic field within the reverberating chamber (RC) to characterise near line-of-sight (near LOS) conditions. This k approach is time effective and granular enough to characterise this working region. A large set of experiments accomplished at the RC of the Università di Napoli Parthenope, formerly Istituto Universitario Navale, demonstrate the effectiveness of the new index.
