T1 O-Type Relativist Corrugated-Waveguide Oscillators JF Telecommunications and Radio Engineering JO TRE YR 2002 FD 2004-04-19 VO 58 IS 5&6 OP 14 AB An efficiency of the relativist Cerenkov effect oscillators has been examined by means of the general excitation equations for longitudinally-irregular waveguides. Based on the partial optimization of the profile of the relativist BWO slow-wave structure it has been shown that 40%- and 60%-efficiencies can be attained both in this particular structure and in reflex-klystron oscillators respectively. In both cases an essential role is played by the forward-to-backward wave conversion and vice versa in regular and irregular corrugated waveguides.
