The external inspirator is available to drive the resonator to produce traveling wave.Under resonant frequency the distortion of resonator reached a peak.
Automatic frequency control (AFC) system is used to adjust the frequency of microwave power source to match the inherent frequency of acceleratory tube.

This paper presents an all-digital close-loop operation based on DSP circuits, which uses the two-frequency serrodyne modulation to modulate and demodulate the optic route.
Abstract: A network model was developed to analyze a piezoelectric source driving a resonantor to investigate the coupling of the piezoelectric loudspeaker with a thermoacoustic resonantor.
Finally, in the micropolis corners you can see ring resonators, which are a conventional (non photonic-crystal) way to achieve a resonant cavity for use in channel-drop filters, etcetera.
Although a key difference here is that the frequency of that external force in general has nothing to do with the resonant frequency of that little oscillator.
And the real heart of the matter comes down to what's sitting in the denominator here, the difference between the square of the resonant frequency and the square of the light frequency.
And to build a little intuition, take a moment to think about what would happen if the frequency of the incoming light was something very close to the resonant frequency of this oscillator.
One thing to note is that if your clock is either fast or slow, it's most likely because the crystal oscillator doesn't oscillate exactly at 32.768 kilohertz due to the geometry and incorrect resonant frequency of tines.
What we found is that the amplitude of oscillation when you shine a light on a charge like this will depend on how close the frequency of that light is to the resonant frequency associated with this spring-like restoring force.
