摘要

The singularities in the spectrum of bulk acoustic phonons polarized in the sagittal plane are investigated on a plate made of a uniaxial ferroelastic material undergoing a proper ferroelastic transition from the paraelectric to the ferroelectric phase. The singularities are induced by anomalies in the reflection of this type of normal elastic vibrations at the crystal boundary.
