In this paper evolutionary computation is applied to the synthesis of planar periodic EBG. We constrained our evolutionary design to the unit cell geometry and used a full–wave MoM to evaluate all individuals. Results show that the resonant frequency is able to approach the desired value, improving the bandwidth.
