| 摘 要： | 圆形槽波导^[1]是一种新型的宽频带、大功率，低损耗和大尺寸波导结构，在毫米波、亚毫米波波段有重要应用前景。利用时域有限差分法（FDTD）分析了圆形皮导的传输特性，计算了圆形槽波导工作在主模TE^[1]11情况下的色散曲线和截止频率，并与已知的理论值相比较，两者一致性好。

| Abstract: | Circular groove guide is one of excellent millimeter wave and submillimeter wave transmission lines, it has characteristic such as low loss, low dispersion, large dimension and high power capacity, etc. This paper presents the analysis of circular groove guide by FDTD method. The cut-off frequency of main operating mode TE 11 is obtained and accords with the theories presented in other papers. |
