Verification approaches for equipment radiated susceptibility on satellite scenarios

The increase of satellite complexity both in terms of mechanical configuration and equipment electronics sensitivities makes the electromagnetic analysis simulation approach a fundamental instrument for EMC verifications on satellite scenarios. This paper presents a general approach used to verify radiated susceptibility levels in terms of electric field based on the selection of the proper electromagnetic solver on the basis of geometry complexity and antenna frequency. Furthermore it is proposed an approach based both on engineering assessment and on empiric measurements useful to calculate the electric field attenuation due to satellite structure apertures (used for cables routing) to determine electric field transmitted inside spacecraft body.
