Considering azimuthal spaceharmonics, the finite size vane model is suggested for vane-loaded helical slow-wave structures in this paper.
考虑角向空间谐波，建立了有限厚度翼片加载螺旋线慢波结构的模型，推导出色散方程。

Itshould be noted that not only the time harmonics but also the spaceharmonics have been taken into consideration in this mathematical model.
值得说明的是这些公式及其推导中既包含了时间谐波又包含了空间谐波。

A harmonic surface charge method, which combine surface charge method with spaceharmonics expansion, was developed for the calculation of 3d magnetic fields of deflection yoke.
