提出了一种用于宽带行波管的E面蛇形折叠型波导慢波结构，并用简单的准横向电磁分析方法研究了该结构的色散和互作用阻抗特性，包括束孔不连续性的影响。通过冷测、传输线参数近似分析、等效电路分析和使用CST微波工作室的三维电磁建模，验证了计算结果。研究了结构参数对行波管带宽展宽的影响。
An E-plane serpentine folded-waveguide slow-wave structure with ridge loading on one of its broad walls is proposed for broadband traveling-wave tubes (TWTs) and studied using a simple quasi-transverse-electromagnetic analysis for the dispersion and interaction impedance characteristics, including the effects of the beam-hole discontinuity. The results are validated against cold test measurements, an approximate transmission-line parametric analysis, an equivalent circuit analysis, and 3-D electromagnetic modeling using CST Microwave Studio. The effect of the structure parameters on widening the bandwidth of a TWT is also studied.
