In the traditional clustering methods based on grid and density,the interval and the density valve needs to be input with unsmoothed cluster,wrong judgement of clustering boundary.

传统的基于网格与密度的聚类方法需要用户输入间隔距离和密度阀值参数，聚类的结果不平滑，不能很好地判断边界对象的网格归属。

The full space calculation model, which suits for the asymmetric structure sometimes even including air below the surface of medium, can enable simulative result to approach real one. The FDTD algorithm based on the mixed ABCs is proper to calculate the transmission line where the electromagnetic wave is transmitted in order to send electromagnetic energy along central conductor.
