Paper Abstract

A stack-by-stack synthesis method for antireflection coatings at any light incidence is presented. It is based on the idea that the original multilayer system can be partitioned into some cascaded few-layer stacks. Each stack is designed by solving a simpler auxiliary antireflection design problem, in which the indices of incident medium and substrate are defined appropriately. Since the reflectances of the designed stacks will be small but not null, the reflectance of the original system will be low but not optimal. However, it can be considered a good starting point for the final refining. The basic idea is exploited in a stochastic environment in order to overcome the drawback due to the presence of many local minima.
