皱纹波导的阻抗是一个复数,其实部决定了波导的损耗,虚部决定了波导的相移或延迟因子,而当软波导与其特性阻抗相近的硬波导连接时,接头处的反射或驻波系数既同软波导阻抗的实部有关,而且更主要的是同它的虚部有关。因此,精确测定软波导的复阻抗无论对于软波导的设计,还是对于软波导的应用都是很必要的。本文以皱纹矩形软波导为例,说明应用测量线测定其复阻抗的方法。虽然现在测量波导复阻抗的方法很
The impedance of the corrugated waveguide is a complex number. The real part determines the waveguide loss. The imaginary part determines the phase shift or delay factor of the waveguide. When the soft waveguide is connected with a hard waveguide with similar characteristic impedance, the reflection or standing wave coefficient Both with the real part of the soft waveguide impedance, but more importantly with its imaginary part. Therefore, the accurate determination of the complex impedance of the flexible waveguide is very necessary for both the design of the flexible waveguide and the application of the flexible waveguide. In this paper, a corrugated rectangular flexible waveguide is taken as an example to illustrate the method of measuring the complex impedance with a measuring line. Although the method of measuring waveguide complex impedance is now very much
