一种柱-锥盘荷波导的色散关系

Dispersion relation of a cylindercone diskloaded waveguide structure

摘要: 导出了柱-锥盘荷波导的色散方程，并通过数值计算分析了这种慢波结构的几何参数对相对论行波管运行频率和通带的影响，与柱形盘荷波导相比，这种慢波结构的上截止频率高于柱形盘荷波导,因此，可以得到较高的运行频率和较大的通带,为设计这种慢波器件提供了依据。

Abstract: This paper presents a comprehensive theoretical treatment for dispersion relation of cylindercone diskloaded waveguide. The results of the numerical computation for various parameters of the devices are given, the TM mode is analyzed, and compared with the cylinder diskloaded waveguide. It can be operated on higher frequency with broad band than cylinder diskloaded waveguide.
