Low Loss Crystal Systems

The Journal of the Acoustical Society of America, 1949
Some aspects of the theory of low loss crystal systems are presented. The effect of small losses on the resonant frequency, the difference between the resonant and antiresonance frequencies, and the electrical impedances at resonance and at antiresonance, is calculated. A quality factor is defined and related to the mechanical loads on the crystal.

Low loss acoustic device

Acoustic wave devices are disclosed. The devices include a substrate, a bi-layer reflector and an acoustic wave resonator. The bi-electric reflector is above the substrate and includes a first layer that has a first acoustic impedance, and a second layer that has a second acoustic impedance lower than the first acoustic impedance. The first layer has a
