【摘要】 本文运用螺旋坐标系计算了带状螺旋慢波线结构的耦合阻抗．本文给出了螺旋带缝隙内的电磁场解，因而明确地计算了螺旋带缝隙内的传输功率，分析了这一部分功率对耦合阻抗的影响．结果发现螺旋带缝隙内的传输功率对耦合阻抗的影响较大，包括这一部分功率后，理论与实验符合得很好．更多还原

【Abstract】 In this paper a practical tape shape helix slow wave structure is calculated for coupling impedance with a new developed coordinates helical coordinates.Particularly the electromagnetic field solution in the gap between the helix is given,the propagation power within this area and its effects on coupling impedance has been calculated and discussed more rigorously than by previous researchers.更多还原
