摘　　要：本文介绍螺旋折叠圆波导慢波结构的主要特性：色散关系和互作用阻抗。计算表明，该电路在γα（径向传播参量）较小时，色散强于螺旋带慢波线，但其互作用阻抗较高。若它工作于较大γα值，色散变弱，而仍具有高的互作用阻抗，故可作为宽频带高功率微波放大的电路。The main properties of helically wrapped circular waveguide slow wave structure,including the dispersion relation and interaction impedance,are presented.It is shown that the helically wrapped circular waveguide has a higher interaction impedance,although it is more dispersive than the tape helix at low γα(radial propagation parameter).Then it would permit operation at a higher γα,where low dispersion makes moderately broadband high-power microwave amplification possible.
