中文摘要：

为了克服单模近似法在分析矩形栅慢波系统高频特性时的局限性，采用了一种新的方法，即在表示槽区内的场时，保留其高次项，表为一无限本征驻波之和的形式，利用场匹配法得到其色散特性，进而求得耦合阻抗．然后针对矩形栅慢波系统进行了数值计算，并分析了金属栅的几何尺寸对系统高频特性的影响，以作为器件设计的参考。设计出3cm、8mm波段的矩形栅高频结构模型，进行实验测量，得到的实验值与理论值符合良好。

英文摘要：

In order to overcome the limit of Single-Mode Approximation （SMA）, this paper adopts a new method that when expressing the fields inside the grooves, the higher orders are retained as an infinite sum of standing eigen-waves. The dispersion relation is obtained by field-matching method, while the coupling impedance is subsequently obtained from the relevant equations. A lot of numerical computations and analysis are done for rectangular grating slow-wave system. And the effects of the geometrical characteristics of the grating are analyzed. Finally, rectangular waveguide gratings at 3 cm band and 8 mm band are designed and measured, experimental values match theoretical values very well.
