Abstract :
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.
