“…In the analytical model of this chamber, all loss mechanisms are taken into account in terms of an equivalent finite conductibility of the walls [21]. More details on the RC characterization, including quality factor, working frequencies, the well stirred conditions and the performances of the multiple monopole source stirring technique can be found in [24–26].…”

This paper presents a general and quasi-analytical method aimed at reconstructing the electric field radiated by equipment under test (EUT), in free space through the knowledge of the values of the electric field sampled on the walls of a rectangular metallic enclosure. The algorithm is based on a set of equivalent magnetic and electric currents, regularly placed in a sub volume of the chamber, whose values are determined to reconstruct the electric field due to the EUT on the samples. Results show that the method is general because it can be applied to a wide set of EUTs, but it is also flexible because it is able to exploit some a priori knowledge of the source to improve its accuracy and efficiency.

“…The limitation of this approach is due to the presence of losses from different sources (walls, antennas, apertures, gaskets) that cannot be modelled as is. For this reason, a classical approach in RC chamber [22] modelling is used: the chamber's walls are simulated with an equivalent conductivity that permits us to obtain a chamber with the same Q-factor as the real one, for each frequency [25]. In particular, in our chamber, in order to obtain the same Q-factor, the conductivity of the walls is modelled with a value that is reduced by a factor of 10 with respect to the σ of the galvanized steel.…”

This paper presents a novel algorithm to emulate the Rician K-factor of a wireless communication environment using a reverberation chamber. In particular, it was focused on the frequency bands used by 5G technology for data transmission. Unlike the current state of the art, the increase of the Rician K-factor is not achieved by inserting lossy material in the chamber, but through the proposed algorithm, which selects a subset of electromagnetic field realizations inside the chamber. The algorithm was first applied to the results of a simulation obtained by using an analytical model that predicts the main physical quantities inside a rectangular cavity where a multiple monopole source stirring action is implemented. Subsequently, the robustness of the algorithm and its applicability was tested on a set of data retrieved from experimental measurements. In all of the considered scenarios, the validity of the proposed method was demonstrated.
