Abstract: Graphics processing units (GPUs) have increasingly become an attractive alternative to central processing unit (CPU) for some of compute-intensive and parallel tasks. This paper presents application of GPU technology to speed up numerical electromagnetic code (NEC) electromagnetic simulation. Then the GPU-NEC was used to evolve antenna. In comparison of the CPU computing, the relative error of the GPU computing shows in the range of allowable. The best result of GPU computing successfully obtains a speedup of nearly seven times compare to without GPU computing. In application of the GPU-NEC in evolving antenna the acceleration about seven times as well.

Keywords: graphics processing units; GPUs; antenna design; evolutionary algorithms; numerical electromagnetic code; NEC; electromagnetic simulation.
