The quartz crystal resonator (QCR), as its acronym implies, is a resonant physical device. Many of its behaviors and properties can be understood physically by examining its resonant behavior. The basic principle of operation for a generic acoustic-wave sensor is a traveling wave combined with a confinement structure to produce a standing wave whose frequency is determined jointly by the velocity of the traveling wave and the dimensions of the confinement structure. The most basic way of resonator modeling consequently requires applying the theory of wave propagation whereby considering material properties and geometric dimensions of the resonator. As another successful way, there is an electrical equivalent circuit often used to characterize the resonance. For these reasons, a closer inspection of the phenomenon of resonance is useful.
