Abstract :
A genetic algorithm (GA) design methodology is presented for the synthesis of doubly periodic all-dielectric frequency selective surfaces (DFSS). The GA is used to optimize the dielectric constants of the material as well as the topology of the unit cell to produce the desired frequency response. The finite element-boundary integral method (FE-BI) is employed to evaluate efficiently the fitness of a candidate design.
