摘　　要：文中对波动方程差分解法进行了研究 ,探讨了理想导体表面、棱以及顶点对电场传播的影响 ,提出了一些有意义的合理假设。最后将上述方法和假设应用于波导T形接头的分析 ,得到了可信的计算结果。由计算结果也可以看出 ,没有采取匹配措施的波导T形接头的性能不是很好 。In this paper, the wave equation finite difference method is analyzed in XYZ system and the influence of perfect conductor surfaces and edges on electromagnetic fields is also discussed. Finally, some hypotheses are brought forward and used in analyzing the waveguide T-Junction. The computation results are verified by comparison with results obtained by some electromagnetic field simulate softwares.
