RT Journal Article ID 2631ea2b0e970494 A1 Kurin, V. G. A1 Korneenkov, Victor Konstantinovich T1 PERFORMANCE OF DIFFRACTION RADIATION OSCILLATOR ON HIGH-ORDER SPATIAL HARMONICS JF Telecommunications and Radio Engineering JO TRE YR 2010 FD 2010-08-07 VO 69 IS 10 SP 909 OP 916 K1 spatial harmonics K1 starting current K1 periodical structure AB The output characteristics of the diffraction radiation oscillator working on high-order spatial harmonics are studied. For the 1st and, in particular, the 2nd spatial harmonics of the same oscillator, the levels of the output power and the starting current are compared, and the gains from the operation on the 2nd harmonic are shown. A physical interpretation is suggested for the mechanism providing enhanced oscillator efficiency on high-order spatial harmonics.
