Abstract
This paper describes a novel method to reconstruct the radiated emission of a device under test placed in a reverberation chamber equipped with multiple monopole source stirring technique. The method is based on the measurement of the normal component of the electric field, collected close to the walls of the chamber by the monopole antennas. The main improvement from the previous formulation of the method is that the only knowledge of the amplitude of the electric field is sufficient to reconstruct, within a predictable range of uncertainty, the maximum level of the radiation of the device over all the directions at a given distance. The consequent advantage is that the method is immediately usable in a realistic scenario for emission tests, where an EMI receiver or a spectrum analyzer are used to measure the electric field and therefore only the amplitude of the field is retrieved.
