- Abstract:
- Mode matching method is used to analyze the scattering characteristics of the circular-to-circular groove waveguide junction. Matching the electric fields and magnetic fields at the boundary of the junction, and multiplying the mode functions of the circular waveguide and circular groove waveguide on both sides of the boundary equation, the scattering matrix equation is obtained, the scattering coefficients can be obtained from the equation. Then the scattering characteristics of the iris with circular window in circular groove waveguide are analyzed. At last the convergent problem is discussed; when choosing a suitable mode group, convergent numerical results are obtained, and the frequency response of the iris’ scattering coefficients is also given.
- 运用模式匹配法, 分析了圆-圆形槽波导结的散射特性.在圆-圆形槽波导结上匹配电场和磁场的边界条件, 然后在边界方程两边同乘以圆波导和圆形槽波导的模式方程, 得到了散射矩阵方程, 结的散射系数可由此方程得出.然后分析了圆形槽波导中放置圆形膜片的散射特性.最后讨论了数值计算结果的收敛性; 当选择恰当的模式组时, 得到了收敛的数值结果, 同时给出了膜片散射系数的频率响应结果.
