Measurement of dispersion and azimuthal interaction impedance of vane-loaded coaxial wave guiding structures

Vane-loaded coaxial structures have been analyzed for dispersion and interaction impedance [1-2]. However the measurement of these parameters has not been reported. A method of simulated measurements was reported [3], in which the dispersion and azimuthal interaction impedance were obtained by using 3D-simulation software as a tool for conducting simulated experiment. In the present paper the results obtained by actual measurements are compared with simulation results obtained using CST-Micro-wave studio.
