acoustic wave [ə′küs·tik ′wāv] (acoustics) An elastic nonelectromagnetic wave that has a frequency which may extend into the gigahertz range; one type is a surface acoustic wave, and the other type is a bulk or volume acoustic wave. Also known as elastic wave. How to thank TFD for its existence? Tell a friend about us, add a link to this page, add the site to iGoogle, or visit webmaster's page for free fun content. |

The elastodynamic model is used to calculate the
dispersion of surface acoustic waves in the film and also provides an
efficient algorithm for the inverse problem of characterizing the film
from measured values of the dispersion. Acoustic wave detectors -- sensitive scientific instruments about
the size of a microscope slide -- rely on ultrasonic waves to detect a
variety of materials. Module content typically
includes multiple die-level devices created using TriQuint's
highly-regarded gallium arsenide (GaAs) processes for the power
amplifier and matching circuitry, as well as surface acoustic wave (SAW)
technology for filtering and duplexing. |
