Abstract

The faceted surface is used in mesh reflectors to reflect electromagnetic (EM) signals. A mesh reflector design method is developed with a triangle-quadrangle mixture based on electromagnetic performance. Incorporating the principles of structural topology optimization for integer optimization of nodes and utilizing Delaunay triangulation for facet partitioning, quadrilateral facets criteria for mixed mesh topography, along with Lloyd's algorithm optimization for uniform design, we propose a mesh reflector design method distinct from traditional empirical formulas. An optimization model is established and used for comparative analysis. The results indicate that the proposed method significantly reduces the number of facets and cables while ensuring EM performance. It achieves a hybrid design of triangular and quadrangle topologies and expands the solution space for mesh surface design. The feasibility and effectiveness of this method are validated.
