“…where U s is the initial power density [W/m 3 ] [9]. The noise floor of the measurement equipment ultimately contributes to a non-exponentially decreasing component in the slope of the PDP [10] [11]. Since τ RC and U s are derived through a least squares fit of the exponential decay portion of the PDP(t), a fitting range is chosen by inspection to both neglect the early-time behavior and the behavior as the PDP approaches the noise floor.…”

“…For measuring the performance of wireless devices, it is important to set up the chamber correctly in terms of antenna placement and orientation, number of mode-stirring samples, etc [10]. Earlier work describes how to do this with and without known lossy materials such as RF absorbers present in the chamber, taking into account important metrics like spatial uniformity and chamber decay time (τ RC ) [9] - [12].…”

“…The PWB model provides very fast results, but it cannot account for the inhomogeneity in the diffuse field arising from any loss in the cavity. Examples of where this limitation is potentially significant include reverberation chamber (RC) measurements made with significant loading to replicate multipath environments for antenna measurements and estimating the exposure of people to diffuse fields in enclosed spaces [2], [3].…”

 Diffusion equation based modeling has been proposed for mapping the reverberant component of the electromagnetic field in enclosures at high frequencies. Preliminary evaluation of the electromagnetic diffusion model using a dimensional reduction approach showed promising results compared to measurements. Here we develop a full three-dimensional diffusion model of the experimental canonical test cases considered in the preliminary evaluation and obtain finite element method solutions. The results are compared to those of the two-dimensional models. We find that the two-and three-dimensional models are generally in excellent agreement for the pseudo two-dimensional test-cases considered. Some deviations between the two-and threedimensional models are observed due to the fact the point source must be effectively represented by a line source in the reduced model. The three-dimensional model is still highly efficient compared to other applicable techniques, offering the prospect of a radical reduction in the resources required for simulating reverberant fields in electrically large structures.
