Feasibility study of a graphene-loaded composite for improved EMI performance of satellite cavities

The continuous development of lightweight composites with enhanced electromagnetic properties remains a persisting challenge in satellite applications. To address this issue, the integration of a graphene-filled polymeric paint has been proposed as a feasible solution for controlling electromagnetic interference (EMI) effects, particularly in satellite scenarios where the smaller size and reduced cost compared to standard electromagnetic shields can offer significant advantages. In this paper, the electric field generated by the spurious emissions from internal units of a Low Earth Orbit (LEO) satellite operating at 162 MHz is evaluated, and the successful integration of a graphene-filled polymeric paint within a satellite cavity to mitigate EMI on the Automatic Identification System (AIS) receiver unit is demonstrated.
