| Abstract: | A geometric degeneracy that can occur in natural frequencies and external Q factors of magnetron‐type cavities is studied. We analyze the causes of its appearance and consider its feasibility to enhance the efficiency of the cavity design. Transcendental frequency‐independent equations, the solutions of which can be easily obtained, and efficient estimates based on rigorous analysis are suggested to predict the existence of the degeneracy. © 2002 Wiley Periodicals, Inc.
