The estimation of optimal parameters with the analytical model regarding nonlinear electron motion dynamics is fulfilled for the submillimeter-wave M-type oscillator tor operating on frequency about 0.33 THz with anode voltage 13 кV and magnetic field 0.7 Т. Revealing from this model, the magnetron interaction space geometry providing the effective electron interaction with a high-frequency field on (+1) spatial harmonic of π-mode oscillations is proposed for the drift-orbital resonance regime.
