(Color online) Schematic of the reentrant linear magnetron modeled by the two-dimensional MAGIC PIC code in the plane. The coordinate system is a Cartesian coordinate, and the length of the axis is considered as in the simulation.
(Color online) Vector plots of the electric field of (a) the mode and (b) the neighboring mode in the plane simulated by using the three-dimensional EM simulation.
Dispersion relation and the Ohmic quality factors of a ten-vane reentrant resonator as a function of phase shift between vanes. The rectangular and triangular dots indicate the resonant frequency and Ohmic quality factor, respectively.
Normalized electron density measured in the interaction space at the simulation times of 1 and when the injected current density of and the beam voltage of are used.
