The theory is developed which describes evolution of an RF generator (auto-oscillator) coupled by a waveguide with an outer
resonator. The treatment is based on a simplified universal method which implies the following conditions to be valid: 1)
the resonant load Q is much higher than that of the generator, 2) the generator-load coupling is weak, but non-zero, and,
3) the system evolution time is
... [Show full abstract] much longer than the lifetime of active medium particles. When the parameters of such a system,
including the wave delay time, belong to an optimum region, the generator, after a delay, becomes frequency pulled to the
outer resonator.
