Abstract :
A novel evolutionary optimization technique is presented in this paper by introducing its applications in some representative electromagnetic design problems. The kernel of the optimizer applies particle swarm optimization (PSO) algorithm, and the fitness functions are evaluated by finite difference time domain (FDTD) simulations. The algorithm is executed on parallel clusters to reduce computational time caused by foil-wave analysis. The performances of the optimized patch antennas and electromagnetic band-gap (EBG) structures validate the robustness of the algorithm in various electromagnetic applications.
