Differential Theory with Genetic Algorithms in Design Periodic Absorbers

摘要：

A differential theory and a real-valued genetic algorithm are implemented to design the periodic gratings. The differential theory is well established to analyse the periodic structures and to compute its reffiectivity. With genetic algorithms, we search the optimum geometry characteristics (thickness and period) and material composition (permittivity and permeability) which minimize the reffiectivity on a wide frequency band. We apply our study to optimize a stuck structure constituted by a periodic grating and homogeneous layers. Numerical results of the frequency behaviour of the optimized structures are presented.
