摘要
A multipactor breakdown analysis is presented for the fundamental mode of an elliptical waveguide. A 2-D geometry of the waveguide is considered, and the numerical method of Monte Carlo based on the effective-electron approach is used. Multipactor breakdown threshold prediction is performed using the enhanced counter function. The radio-frequency (RF) breakdown threshold is obtained as a function of the frequency-gap product for different values of the ellipse eccentricity. The results indicate that decreasing the ellipse eccentricity increases the RF breakdown threshold. The results are compared with those for circular and parallel-plate waveguides.
