加载单脊波导的微波色散特性研究

The Microwave Dispersion Study of the Loaded Single Ridged Waveguide

理论上分析计算了所设计的加载ＬｉＮｂＯ３晶片的单脊波导在微波Ｘ波段的色散特性，实验上测量了此色散特性，两者具有较好的一致性，并表明该波导实现了微波与光波的速度匹配而成为宽带行波光调制器。

The X-band microwave dispersion of the loaded single ridged waveguide is calculated and measured.There's good agreement between the two results,the velocity of light and microwave is matchable in rather wilde range of X-band for the designed waveguide modulator,and it provides the novel broadband travelling waveguide modulator.
