Radio-frequency superradiance in a resonator
Kiselev Yu. F. , Aliskenderov E. I.
Modified Bloch equations are derived with allowance for the phase-frequency characteristic of the oscillatory circuit. It is shown that nonlinear processes of radio-frequency super-radiation (SR) and maser oscillation (MO) as well as the oscillating frequency are closely related to the phase characteristic of the circuit; this makes it possible in an experiment to separate the SR eifect from the MO effect.
