Abstract
Genetic algorithm (GA) has been applied to the design of multi-layered planar and cylindrical absorber structures. Corrugated coatings with non-planar shape profile offer an additional degree of design freedom. In this paper, we apply GA to design the optimal shape for a corrugated coating under oblique incidence. To predict the performance of each shape, we employ a full-wave electromagnetic solver. GA with two-point crossover and geometrical filtering is implemented to achieve effective optimization. The optimized designs for different polarizations are presented.
