Particle-in-cell simulation of 100 GHz reentrant linear magnetron

100 GHz linear magnetron employing the ten-vane reentrant resonator is investigated by using a two-dimensional particle-in-cell simulation. The dynamics of electron beam, the time variation of electric energy in each vane, and the generated power density are examined when the injected current density is varied. The maximum power density is 180 mW/mm
²
at 100 GHz when the current density of 80 A/cm

is used.
