Synthesis of EBG surfaces using evolutionary optimization algorithms

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.
