Offset-Feed Surface Mesh Generation for Design of Space Deployable Mesh Reflectors

Surface mesh geometry is crucially important to the performance of deployable mesh reflectors. This paper presents new results from a continued research effort to design the pseudo-geodesic mesh geometry for offset-feed parabolic mesh reflectors and to fulfill the operating frequency requirements in related applications. The proposed method is applied to two offset parabolic reflector examples. The geometries so generated satisfy the surface accuracy and offers the exact presentation of desired working shape at its best-fit surface. Additionally, a comparative discussion shows that the design results by the proposed method always have the simplest mesh topology, the minimum total length, and competitive surface RMS errors.
