摘要 通过切比雪夫多项式展开螺旋带上的面电流,用真空层模拟螺旋带的厚度、均匀分层介质等效介质夹持杆、用无限多个无限薄的翼片等效实际翼片,得到了色散方程、平均耦合阻抗和衰减常数的表达式。与实验数据相比,结果接近实验值,该文提出的方法对实际螺旋线慢波系统的设计具有重要的指导意义。 By expanding the surface currents on the helix tape in a series of chebyshev polynomials,simulating the helical thickness with vacuum layer, equaling the rods with multiple azimuthally symmetric layers and considering the loaded-vanes, the dispersion equation,interaction impedance and attenuation constant of helical slow wave structure with arbitrary tape width,supported by a radially stratified dielectric layer which is adjacent to the loaded vanes and enclosed by a metallic shell are obtained. The calculating results show good agreement with the experiment results. The theory can provide a strong basis for design of the helical s1ow wave structure.
