RT Journal Article ID 12432b2f796383e5 A1 Yeryomka, V. D. A1 Gurko, A. A. T1 Preferable Conditions for Excitation of Operating Mode in Non π-Mode Magnetron JF Telecommunications and Radio Engineering JO TRE YR 2009 FD 2009-10-21 VO 68 IS 13 SP 1199 OP 1211 AB The reasons for restricting the domains of existence of the doublet oscillation modes as a function of the magnetic field in periodic vane-type cavity oscillating systems of millimeter-wave magnetrons are analyzed. Analytical expressions were derived to describe the relationship between the upper domains of the operating mode existence with the oscillatory system parameters and the HF-field structure in the oscillators’ interaction space. A criterion for evaluating the stable operating mode excitation is proposed. This criterion corresponds to the magnitude of the relation between the harmonics amplitudes of competing and operating modes on a operating mode synchronization radius.
