“…where each term can be evaluated solving the integrals in ( 5) and (6). In particular, the electric field radiated by the equivalent currents of the i-th sub-area in a generic point P(x, y, z) is expressed by ( 7), ( 8) and ( 9).…”

“…For this reason, how to correlate the measurements performed in these sites to OATS conditions has been investigated. In this direction, [1][2][3][4][5][6][7] introduced a set of equivalent sources to replace the equipment under test (EUT) and to extrapolate the radiation in free space conditions from the measurements performed in these alternative sites.…”

This paper presents an optimization of a method to reconstruct the radiated emissions of an equipment under test by the measurement of the electric field samples collected on the walls of a reverberation chamber. This means that only the orthogonal component of the electric field is necessary to obtain the radiative behavior of the device in free space conditions. The use of the equivalence principle allows one to reduce the number of equivalent sources used to reconstruct the radiation of the device. In fact, in the previous version of the method, the sources are placed into the entirety of working volume of the reverberation chamber. In the current version of the method, only the surface surrounding the equipment under test is discretized. The analytical implementation of the method is proposed for a particular stirring action: the multiple monopole source stirring technique. This technique is based on an array of monopoles placed onto the walls of the cavity, and therefore no further hardware is needed for the reconstruction of the radiated emissions. The method is experimentally validated in a real scenario.

“…GTEM cell measurements of an EUT were also proposed for predicting the equivalent OATS radiated field [14,15]. The EUT is modelled by equivalent sources and the algorithms used are based on several a priori assumptions on amplitude, phase and position of the multipoles and their influence on the simulated OATS field.…”

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.
