A bridge method for simultaneous measurements of coupling coefficient and loaded Q of a single‐ended cavity

A bridge method which allows the simultaneous measurements of the coupling coefficient and the loaded Q of a single‐ended cavity is described. The measuring system consists of a ``magic T'' bridge and incident power monitor circuits. Two collinear arms of the magic T are terminated by the cavity under measurement and the built‐in short at equal distances. Measurements are made by comparing the reflected power from the bridge with the incident power on the cavity.
