Figure 1

Concept of Q-factor control using a variable phononic bandgap. (a) A Q-factor is “not” observed because of rejecting external vibrations in the case of the resonant frequency is “inside” the phononic bandgap. (b) The Q-factor is observed because of accepting external vibrations in the case of the resonant frequency is “outside” the phononic bandgap.
