研究了三种新型的曲折波导慢波系统,分别是曲折双脊波导、脊加载曲折波导和矩形槽加载曲折波导。给出了其高频特性的理论和仿真结果。然后介绍了基于常规曲折波导和脊加载曲折波导慢波系统的Ka波段行波管的实验结果。
Three new types of tortuous waveguide slow-wave systems are studied. They are zigzag double-ridge waveguide, ridge-loaded zigzag waveguide and rectangular slot-loaded zigzag waveguide. The theoretical and simulation results of its high frequency characteristics are given. Then, the experimental results of Ka - band traveling wave tube based on the conventional tortuous waveguide and ridge - loaded tortuous waveguide slow - wave system are introduced.
