Influence of AlN quality on the transverse and longitudinal coupling coefficients of acoustic devices

TL;DR: In this paper, the transverse and longitudinal piezoelectric response of AlN polycrystalline thin films is analyzed by means of measurements in surface acoustic wave and bulk acoustic wave (BAW) devices fabricated on films of identical characteristics.

Active Wave Propagation and Sensing in Plates

TL;DR: In this article, a model is developed to simulate asymmetric wave propagation in a panel and to produce a movie of the wave motion, where the propagation, reflection, and interference of the waves are represented in the model.

Reflection of normal acoustic waves in thin plates from a grating with a periodically distributed mechanical load

TL;DR: In this article, the effects produced by short-circuiting of the plate surface and by the elastic load on the impedance ratio of adjacent plate segments are in opposition to each other, and hence, for each wave type, there is a certain value of the strip thickness at which the reflection coefficient becomes equal to zero.
