| 摘要: |
| 采用有限差分法分析单脊金属加载矩形波导的模式特性,得到单脊金属加载矩形波导的基模和第一个高次模均是TE模,两个最低模均是TM模;基模截止波数kc=0.20056 rad/mm,第一个高次模截止波数kc=0.46731 rad/mm,与Ansoft HFSS仿真软件得到的结果基本一致。 |

| Abstract: |
| Transmission characteristics of the single-metal-ridge rectangle waveguide were analyzed using finite difference method.The field distribution and dispersion characteristics of this waveguide was obtained.The computed results are in good agreement with the HFSS simulation. |
| Key words: ridged waveguide finite difference method field distribution dispersion characteristics |
