Vane-Loaded Helical Slow-Wave Characteristic Analysis Considering Helical Tape Thickness

  • 摘要: 考慮非翼片區(qū)角向高次模式以及螺帶厚度，運(yùn)用場(chǎng)匹配方法參考脊加載環(huán)板慢波結(jié)構(gòu)的邊界條件推導(dǎo)得到翼片加載螺旋慢波結(jié)構(gòu)的色散特性方程；并運(yùn)用MAFIA軟件對(duì)該結(jié)構(gòu)進(jìn)行模擬計(jì)算，將理論結(jié)果與模擬計(jì)算進(jìn)行比較，其誤差范圍基本滿(mǎn)足設(shè)計(jì)精度的要求，并討論了不同翼片結(jié)構(gòu)參數(shù)對(duì)色散特性的影響，為各種類(lèi)型的翼片加載螺旋慢波特性的計(jì)算提供了一種參考方法。
    Abstract: Considering azimuthal higher order modes in non-vane area and helical tape thickness, using field matching method and boundary condition of the ridge-loaded ring-piano slow wave structure, the dispersion equation of vane-load helical slow-wave structure is obtained. The numerical simulation for the vane-loaded helical slow-wave structure using MAFIA software is done. The theory calculation results are compared with the simulation results. Their errors reach the request of design precision. The effect of the dispersion is discussed in the different parameters of the vane structure. The instruction method also is provided for other types vane-load helical slow-wave structure.
