AB The experience of developing magnetrons intended for the short-wave part of millimeter (mm) wave band proves that the most advantageous characteristics are achieved by interaction between an electron beam and a lower spatial harmonic of a degenerate oscillation mode. In commercial production, some drawbacks of this mode are eliminated by including driving inhomogeneities into magnetron's resonator system. These inhomogeneities eliminate the
intradoublet competition at the operating oscillation mode as well as the competition with the doublet components of the high-voltage mode, i.e. the competitor. The calculation procedures reported in the papers related to inhomogeneous resonator systems have certain restrictions,
which make them inapplicable at such a decisive development stage as an analysis of the effects exerted by driving inhomogeneities on the structure of a high-frequency (HF) field of the slowing system. In this paper a new calculation method is suggested, which utilizes the field theory and allows to detect all eigen frequencies and the corresponding HF-field distributions in a slowing system of a magnetron with driving inhomogeneities. The considerations are illustrated by an example calculation of a HF-field distribution and a spatial harmonics
spectrum of the slowing system of the 2-mm magnetron with the driving inhomogeneities. The allocations of the driving inhomogeneities are compared in various combinations. A novel method was developed enabling calculation of inhomogeneous resonator systems for
magnetrons operating in the short-wave part of millimeter wave band.
