Abstract By using the method of transverse-section, the reflective coefficient of diffraction in the open-end of resonators with slowly varying eross-section under general unsym-metrical mode condifions have been found by introduction of a "phase correction factor". Diffraction boundary conditions in the open-end are obtained, and can be used to solve multimode problems. Several different types of open resonators are studied, and methods of engineering calculation also briefly discussed.
