Reverberation chamber for electromagnetic compatibility testing of electric thrusters

Abstract The need for electromagnetic compatibility (EMC) of electrical devices on satellites increases dramatically as the number is rapidly growing and density satellite due to their miniaturization. Thus, EMC electric propulsion system becomes an important issue a safe reliable operation satellite. In particular, this also concerns system. Since thrusters usually be operated in vacuum, dedicated facilities are required assess EMC. Here, we present how common cylindrical vacuum vessel can converted into reverberation chamber suitable pre-compliance testing thrusters. We describe validate its principle discuss limitations. Finally, show first measurement results radiated emission measurements thruster compare those with data obtained same semi-anechoic where inside metal-free fires larger outside chamber.
