A 35 GHz 3 kW spatial-harmonic magnetron employing 20-vane resonator is numerically and experimentally investigated. Simulated output power is 3.2 kW at beam voltage of 6.5 kV and anode current of 4 A using 3D PIC simulation. The measured resonant frequency for operation mode of p = 16 is 34.96 GHz.
Figure 5. The dispersion relation obtained by 2D field theory, 3D FDTD simulation, 3D PIC simulation, and the experimental measurement. The resonant frequencies are shown as a function of phase shift between anodes.
