Full-Wave Analysis of Slotline Using Time-Domain Finite-Difference Method

应用时域有限差分法计算了槽线的传输特性和色散特性 .由于采用了改进的色散边界条件 ,改善了槽线的高斯脉冲的拖尾现象 ,使计算域大为减少 ,节省了内存空间和计算时间 ,更方便于在个人计算机上运行 .同时较好的边界棱和顶点的处理 。

The transmission and dispersive characteristics of slotline are calculated in this paper. The tail of Gaussion pulse is improved because a modified dispersive boundary condition (DBC) is adopted. It leads to a reduction in computer memory requirements and computational time. The computational domain is greatly reduced to enable performance in personal computer. At the same time because edges of a boundary and summits are treated well, the computational results is more accurate and more collector.
