| 摘 要： | 对曲折矩形槽波导新型慢波系统的高频特性进行了研究，通过理论分析和数值计算，得到了它的色散曲线和耦合阻抗，并分析了结构参数变化时对色散特性和耦合阻抗的影响。曲折矩形槽波导结合了曲折波导散热能力强、色散特性好、容易加工和矩形槽波导单模工作、低损耗、大尺寸等优点，因此这种新型的慢波系统有可能在毫米波及亚毫米波段的行波管中具有较好的发展前景。

| Abstract: | As a slow-wave structure, a novel folded rectangular groove guide was studied theoretically and numerically, the dispersion curves and interaction impedance were obtained. Due to its advantages of high power capacity, weak dispersion, easier fabrication and low ohmic losses, the folded rectangular groove guide would be an excellent slow-wave structure in millimeter and submillimeter wave TWTs. |
