CONSTRAINED OPTIMIZATION OF MULTILAYERED ANTI-REFLECTION COATINGS USING GENETIC ALGORITHMS

Optimization based on genetic algorithms is applied to the design of multilayered coatings, incorporating both coating-geometry and material-property optimization. The latter is based on parametric modeling of dielectric and magnetic properties of homogeneous materials, and effective medium modeling of composites. Our approach treats physical laws to be obeyed by the models as constraints. Moreover, efficiency in thickness is considered in two ways: as an upper-limit constraint, and in multiobjective settings including aggregation and Pareto optimality.
