Effect of High Fourier Harmonics on Characteristics of Corrugated Cylindrical Waveguides
Some aspects of calculating the characteristics of corrugated cavities for second-harmonic gyrotrons are considered. The influence of spatial Fourier harmonics supported by corrugations on cavity eigenfields is studied. In some specific cases, a comparison of the Bloch harmonics method with the spatial harmonics method for low and high radial modes is presented. It is shown that the method of spatial harmonics, as opposed to Bloch harmonics method, provides accurate data on eigenfield distribution along the cross-section of the corrugated waveguide, with the exception of small areas near the edges of the corrugations.
