Narrow-band reflector coatings : design procedures

A class of problems dealing with narrow band reflectors under oblique light incidence has been chosen and a group of design procedures leading to the satisfactory results analyzed. At the beginning targets and restrictions have been set, then design has been performed and at the end selection and conclusions have been done. Two different types of target functions have been chosen. Global search for 50 or more layers varying its optical thicknesses between 0 and l/2 and the needle design method have been applied for the synthesis. Gradient and variable metrics have been used for further refinement. Results were compared and it has been figured out that all used design methods led to similar results for this problem. The discussion how to decide which is the best one has been performed.
