Research on simulation computation of the Q/sub ext/ of cavities

Abstract

The principle of a method of simulation computation of the Q/sub ext/ of cavities, which is based on the relationship of reflectance's phase with frequency, is introduced, and the failure of the method is analyzed. It is concluded by quantitative analysis that the partial inductance coupling and the coupling slots in /spl pi/ mode double-gap cavities may bring about the failure of the method.
