Abstract:

In most of the space systems and space applications, it is not viable to fully seal all external structural enclosures at panel level to maintain a homogenous Faraday cage solution. Hence, it is essential to perform a realistic characterization of the Shielding Effectiveness (SE) of the additional external elements utilized to provide electromagnetic protection. This paper presents, in the frame of the Heinrich Hertz H2Sat mission at OHB, an analysis via different modelling techniques, together with the tests, on various configurations of multilayer insulation (MLI) types which were used for passive thermal control. To conclude, a final correlation exercise of both approaches is carried out, together with a comparison between single and overlapped shields.

1. Introduction

When talking about SE, consideration about how well an enclosure attenuates electromagnetic fields is in place. Referent platform scenarios imply that MLI covers most of the outer panels, except the radiator panels. The mechanism on how MLI is influencing RF energy propagation from outside the satellite to inside is based on the two main contributor effects: reflection and absorption of the incident electromagnetic waves. These quantities are calculated as a function of the angle of incidence for transverse electrical and magnetic polarizations.
