Acoustic Waves

1992
Abstract Synopsis. Acoustic waves will propagate in any medium that possesses some form of elasticity. In solids, which have both a bulk modulus (the reciprocal of the compressibility) and a shear modulus (or rigidity) wave propagation is complex, involving both longitudinal and transverse waves.

Surface acoustic wave element, surface acoustic wave device, surface acoustic wave duplexer, and method of manufacturing surface acoustic wave element

The Journal of the Acoustical Society of America, 2007
A surface acoustic wave element includes a thin film electrode composed of monocrystal aluminum disposed on a piezoelectric substrate. At least one metal of Cu, Ta, W, and Ti is segregated in the thin film electrode composed of monocrystal aluminum. In this surface acoustic wave element, segregation of Cu or the like occurs in the thin film electrode ...

Acoustic waves in a perforated cylinder

The Journal of the Acoustical Society of America
A lumped parameter approach to the problem of acoustic wave scattering by a perforated cylinder has been presented. The proposed framework enables analytical evaluation of the scattering amplitudes of all harmonics and derivation of the dispersion relations for the guided wave propagating inside the cylinder.

Acoustic waves

Abstract In Chapter 14, we turn to acoustic waves. We start by deriving the governing equation for small-amplitude acoustic waves in a gas. Next, we consider simple examples of a one-dimensional acoustic waves, such as waves in an organ pipe.
