Generalized stochastic field model for reverberating chambers

In this paper, we present a new stochastic model to characterize the electromagnetic field in reverberating chambers. The model is physically based and is capable to embody as special cases the reference thermodynamic limit (perfectly stirred case) and the Rician case (presence of unstirred component). The stochastic field model is characterized by the generalized K distribution, i.e., a three parameters probability density function (pdf) that ensures a continuous and physically consistent transition among very different scattering scenarios. Theoretical modeling is supported by means of an experimental study based on measurements made at the UniversitA di Napoli Parthenope, Naples, Italy, formerly Istituto Universitario Navale (IUN), mode-stirred reverberating chamber.
