The Resonant Modes of the Rising Sun and Other Unstrapped Magnetron Anode Blocks

摘要

In this paper an electromagnetic field theory is developed for unstrapped magnetron anode blocks of rather general symmetry, from which the wave‐length spectrum and associated electromagnetic fields can be computed. The method is a generalization of that developed by Clogston (A. M. Clogston, Ph.D. thesis, Massachusetts Institute of Technology, 1941) for the simple case in which all of the side resonators are alike. The characteristics of the rising sun type anode block are discussed in some detail. In addition, the general features of anode blocks having any kind of symmetry are discussed in the limiting case of small anode diameter.
