Resonant frequency and Q of an openended rectangular cavity
Abstract
A field analysis of the TE(10m) resonant mode in an openended rectangular cavity is presented. The cavity geometry consists of rectangular waveguide with thick Hplane bifurcations for the terminations at each end. The bifurcation problem is solved by the method of modal analysis and a resonance criterion is established. Expressions for the cavity fields are written and used to compute stored energy, power lost, and Q. Calculated values for resonant frequency and Q are given and compared with experimental data.
