WebMay 9, 2024 · A bulk acoustic wave is a wave that travels through a piezoelectric material, as in a quartz delay line. It is also known as a volume acoustic wave. In some materials, the wave velocity is greater for bulk acoustic waves than surface acoustic wave because SAW is composed of a longitudinal and a shear wave.
