本文将第一部分给出的分析用于我们通常所感兴趣的实际构造。第一种是双柱情况,每个柱只有一个缝。第二种是具有双缝的单柱。首先用阻抗或导纳矩阵元构成缝隙端口网络,然后由这种网络得到波导障碍物表达式。最后的表达式已被用于得到有关分析的实验证明。 This article uses the analysis given in the first section for the actual construct that we are generally interested in. The first is a double-column case, with only one seam per column. The second is a double column with a double slit. First of all, impedance or admittance matrix elements constitute the port network of cracks, and then get the waveguide obstacle expression from this network. The final expression has been used to get experimental proof of the analysis.
