Abstract: The difference between frequency locking and phase locking of multi-cavity magnetrons (oscillators) is analyzed and the method of computer simulations of the locking phenomena in a virtually prototyped system of the coupled magnetrons operating within the same simulation domain is discussed. It is stated that while the frequency locking maybe demonstrated, if properly designed, by computer simulations of the coupled magnetrons operation during one simulation run only by showing an achievement of the same operating frequency of the simulated magnetrons, the evidence of the phase locking maybe demonstrated after at least two simulation runs by showing an achievement (in both simulation runs) of the same phase difference between simulated magnetrons already operating in the frequency-locked mode. The “phase difference” between magnetrons, θ, refers here and elsewhere below to the phase difference between induced electric field (magnetron) oscillations in the appropriate reference planes of the virtually prototyped system of the coupled magnetrons.
