This study deals with measurement of shielding effectiveness applied to Myriade structure using reverberation chamber techniques.The setup implied to place a field probe inside the satellite structure and to measure only power outside the structure. At first, calibrations were done in order to check field evaluation from received power and to choose the best positions of the probe inside the satellite structure. Then frequency and mechanical stirring were compared in order to minimize the time of the measurement. At last, minimum of shielding effectiveness was studied for several configurations of the structure (open, short-circuited, recovered with multilayer insulation, typical).
