| 中文摘要: |
| 本文研究了基于计算统一设备架构(CUDA)的图形处理器(GPU)对双负媒质(DNG)电磁散射规律的并行计算的实施。由于Z变换理论的时域有限差分法可以计算双负媒质中电磁波的散射和传播,同时在空间上具有天然的并行性,因此非常适用于在GPU上实现并行计算。本文引入Drude模型,给出了左手媒质中FDTD迭代公式,研究了基于GPU的并行FDTD方法,最后通过数值仿真实验以及结果证明该方法的正确性和高效性。 |
| 英文摘要: |
| This paper studies a parallel method of DNG (double-negative) meta-materials on CUDA (Compute Unified Device Architecture) GPU (Graphics Processing Unit). Z-transform is applied to FDTD method to analysis propagation and scattering from DNG materials. As Z-FDTD algorithm has the characteristics of spatial parallelism, it is suitable for execution on GPU. The iterative equations of FDTD based on the Drude model are derived; and parallel GPU-FDTD is discussed. The Correctness and efficiency of this method are testified by simulated experiments |
