Abstract in another language

Piezoelectric components have gained widespread use as resonators, delay lines, frequency filters, and sensors in the frequency range between several MHz and several GHz. The use of the devices as sensors is based on the fact that the properties of acoustic waves depend on the chemical, biological, or physical quantity to be monitored.
This tutorial covers the basic concepts of acoustics needed to understand the working principles of piezoelectric sensors. It includes an introduction into fundamental quantities of continuum mechanics and a discussion of acoustic wave types in anisotropic media. Special attention is paid to boundary conditions and surface loading effects. The eventual aim is to provide an in-depth view of analytical and numerical modeling strategies. The tutorial will be self-contained, but some familiarity with engineering mathematics is assumed and prior exposure to electromagnetic wave phenomena is helpful.
