| 摘 要： | 分析了色散介质时域有限差分的模型,并针对非磁化等离子体给出了的分层线性递归卷积算法。介绍了OpenMP并行设计的基本模型,并将其应用于非磁化等离子体的计算当中。最终通过验证非磁化等离子体的透射电磁波,验证了将OpenMP并行设计应用于色散介质中的准确性,同时依据计算区域大小不同的3个算例验证了该算法具有较高的并行性能。

| Abstract: | This paper presents the model of dispersive medium in FDTD and the PLRC method for unmagnetized plasma.The basic models of OpenMP paradigm is introduced and applied to unmagnetized plasma computation.The accuracy of the OpenMP parallel program when applied to dispersive medium is proved by testing the transmission wave through the unmagnetized plasm,and the high performance of the program is proved by three cases with different sizes of computational regions. |
