Efficient Surface Optimization of Large Dual Reflector Systems

Surface shaping of reflector antennas for creating a contoured beam is an ubiquitous task in the design of modern communication satellites. In this paper, we highlight two major improvements to the state-of-the-art that provides a major increase in computational efficiency—a modern minimax optimisation algorithm for large-scale problems and the implementation of analytical derivatives for simultaneous shaping of the surface of both reflectors in a dual reflector system.
