Designing a contoured beam reflector or performing a direct optimization of a reflectarray requires a mathematical optimization procedure to determine the optimum design of the antenna. A popular approach, used in the market-leading TICRA software POS, can result in computation times on the order of days, due to the optimization algorithm.

The present paper discusses recent improvements, allowing reductions in optimization time by two orders of magnitude or more on several application examples.
