We consider the problem of designing antireflection coatings by numerical optimization methods with merit functions in different metrics. The dependence of the optimal solution on the metrics is investigated through numerical experiments on several types of coatings, using the average and maximal values of the reflected power in the regions of interest. The results confirm existing statements and provide a few new findings, e.g., some specific metrics can yield particularly better solutions than others.
