Abstract

Report presents the results of calculations and numerical modeling of quasi-stationary, nanosecond relativistic X-band and Ka-band BWOs with peak power exceeding 100 MW where magnetic field guided electron beam (0.5-1.7 T) could be created by permanent magnets made of highly-coercivity materials. Magnetic field interpolation of the permanent magnets was used in numerical models of microwave devices (code KARAT). Particle-in-cell simulations have shown that in the frequency ranges of 8 GHz and 37 GHz, and for the B-field below cyclotron resonance value, the same parameters of HPM generation are available as it predicted and/or measured experimentally for prototype models with solenoids fed by DC or pulsed current.
