Phonons in an Entropic Crystal

Physical Review Letters, 2000
Hard spheres crystallize due to purely entropic forces. The underlying excluded-volume interaction is completely anharmonic and the nature of the phonon spectrum is therefore of interest. To measure the single-particle motion and the phonon spectrum by dynamic light scattering we have used a collection of novel techniques including multispeckle cross ...

Phononic crystals

Proceedings of 2003 5th International Conference on Transparent Optical Networks, 2003., 2004
AbstractPhononic crystals are periodic composite materials with lattice spacings comparable to the acoustic wavelength. They are of interest not only because of the profound effects of their periodic structure on wave propagation (e.g., the existence of acoustic band gaps), but also because of potential applications (e.g., their possible role in sound ...

Phonon Spectrum in a Plasma Crystal

Physical Review Letters, 2002
The Fourier spectra of longitudinal and transverse waves corresponding to random particle motion were measured in a two-dimensional plasma crystal. The crystal was composed of negatively charged microspheres immersed in a plasma at a low gas pressure.

Phononic crystal sensors

2012 European Frequency and Time Forum, 2008
A new acoustic microsensor principle is introduced for the first time. It is based on acoustic band gap materials, so-called phononic crystals. The sensor employs features of the band gap to determine properties of one component that builds the phononic crystal.
