本文指出了在RC和PLRC-FDTD分析中，匹配DNG平板的非期望反射，并提出了改进方法。由于原始RC、PLRC-FDTD分析中自由空间和DNG板之间的边界定义不准确，导致出现不期望的反射。为了改善这一问题，本文提出了一种新的无DNG空间边界建模方法，该方法将电场和磁场放置在同一位置。
In this paper, we indicate the undesired reflection from matched DNG slab in RC- and PLRC-FDTD analysis and its improving method is proposed. The undesired reflection occurs due to the inaccurate definition of boundary between a free space and a DNG slab in the original RC-, PLRC-FDTD analysis. In order to improve this problem, we propose a new modeling method for the DNG-free space boundary, in the method, the electric field and magnetic field are placed in a same place.
