| 摘 要： | 时域有限差分（FDTD）算法求解电磁问题时，如果目标结构不能和传统网格体系共形，往往采用局部共形网格或非正交网格算法。详细讨论了二维圆柱坐标系中五角形共形网格算法，该算法能方便地对倾斜薄层媒质或电导率不均匀的倾斜媒质等复杂结构建模,并以锥形电磁脉冲天线为例，验证了该算法的有效性。

| Abstract: | When using the finite difference time domain (FDTD) method to solve the electromagnetic problems, the locally conformal grids are often chosen to conform the shape of the boundary such as a curved or slant plane. Pentagonal conformal grids modeling in the two dimensional cylindrical coordinate are specially discussed in this paper. This model is available not only to the perfectly electrically conducting boundary but also to the more complex structures such as the slant thin material sheets and the uneven specific conductance slant materials. The reflection from the pec conical antenna and the far zone radiated waveform from the resistive loaded conical antenna are taken as examples to validate the effectiveness of the modeling, and the results are good. |
