Abstract
The electromagnetic shielding effectiveness (SE) is essential to a spacecraft, since the electronic equipment of it may be severely interfered by the electromagnetic interference. SE is determined by both the aperture and the cable penetration except the structure material. Former research is mostly on the impact of the aperture. In this paper, both simulations and lab tests are done to investigate the impact of the cable penetration. The results show that the impact of the cable penetration is obvious and non-neglectable, and it is up to 20 dB for the frequency band lower than 1 GHz. The shielding operation can be deployed to reduce the electromagnetic leakage and then SE can be improved by 10–15 dB for the frequency band of 200 MHz–3 GHz. The results also show that the impact is not related with whether a signal is transferring or not in the cable. If there is an original cable perforation and then an additional cable perforation near it does not impact SE obviously. The impact is dependent on the locations of the built-in radiated sources.
