摘　　要：　总结了漏泄同轴电缆的理论研究现状。围绕使用频带和耦合损耗这两个重要电气参数,讨论辐射型漏泄同轴电缆的设计方法。基于周期性槽孔结构的空间谐波的分析,讨论了抑制高次谐波以拓展使用频带的方法。利用时域有限差分方法和Matlab软件计算耦合损耗。The present status of theoretical research on leaky coaxial cables is summerized. Focussing on operation frequency-band and coupling loss the design method for radiation leaky coaxial cables is discussed. Based on the analysis of spatial harmonics of periodically slotted structure the method for extending operation frequency-band through suppressing higher-order harmonics is discussed. And the finite-difference time-domain approach and Matlab software are used to calculate the coupling loss of the cables.
