摘要
本文利用傅立叶级数将损耗介质周期加载圆柱波导结构的场展开,通过分界面上场匹配的模式分析方法得出了TM0n模的色散曲线、电磁场分布以及品质因数等特性参量。编写了程序DDET-TM并计算TM01模的各特性参量,得到的结果与HFSS的仿真结果吻合较好,验证了本方法的适用性。
The Fourier series form is used to express the fields in the dielectric loading periodic corrugated waveguides. The boundary conditions imposed at the interface lead to a linear system of equations, which is appropriately truncated for the numerical implementation. A numerical code (DDET-TM) is developed for the calculation of the dispersion relation, the electromagnetic field components, and the quality factor of the TM0n waves. Based on this formulation, we calculated the characteristic of the TM01 mode. ...
