A new method is proposed for designing antireflection multilayers, characterized by an assigned number of layers and given materials. It is based on a two-stage Monte Carlo exploration of the thickness space. In the first stage, many thickness vectors are generated with a uniform distribution over several appropriate sub-boxes in the thickness space. The sub-boxes with the most promising results are preserved only. The second stage is self-focusing in each surviving sub-box: here, thickness vectors are generated non-uniformly by taking into account the distribution of the merit figure obtained previously. Finally, the sub-optimal multilayer of each surviving sub-box works as starting design for the final refining. As an example, the synthesis of antireflection coatings is presented for Germanium IR optics in the region from 7.7 to 12.3 micrometers.
