DISPERSION CHARACTERISTICS FOR PERIODICAL WAVEGUIDE WITH SLOW-VARYING CROSS-SECTIONS
缓变截面周期波导色散特性的研究

The dispersion equation is derived by using the equivalent circuit method for periodical waveguides with double conical slow-varying cross-sections. Some dispersion curves with different parameters of the construction are calculated. Thus, the theoretic basis is provided for selecting optimum dimensions to realize the wide-band gyrotron designs. Finally, theoretic predication is demonstrated by experimental results.
