Pull-in control in microswitches using acoustic Casimir forces [PDF]
Euro Physics Letters vol. 84 (2008) 48002, 2008 In this paper we present a theoretical calculation of the acoustic Casimir pressure in a model micro system. Unlike the quantum case, the acoustic Casimir pressure can be made attractive or repulsive depending on the frequency bandwidth of the acoustic noise.

Acoustic Casimir Pressure for Arbitrary Media [PDF]
, 2004 In this paper we derive a general expression for the acoustic Casimir pressure between two parallel slabs made of arbitrary materials and whose acoustic reflection coefficients are not equal. The formalism is based on the calculation of the local density of modes using a Green's function approach.

An asymptotic model in acoustics: Acoustic drift equations [PDF]
The Journal of the Acoustical Society of America, 2013 A rigorous asymptotic procedure with the Mach number as a small parameter is used to derive the equations of mean flows which coexist and are affected by the background acoustic waves in the limit of very high Reynolds number.

Integration of technologies for understanding the functional relationship between reef habitat and fish growth and production [PDF]
, 2006 Functional linkage between reef habitat quality and fish growth and production has remained elusive. Most current research is focused on correlative relationships between a general habitat type and presence/absence of a species, an index of species ...

Acoustic diagnostics of femtosecond laser filamentation [PDF]
arXiv, 2023 The promising application of femtosecond laser filamentation in atmospheric remote sensing brings imperative demand for diagnosing the spatiotemporal dynamics of filamentation. Acoustic emission (AE) during filamentation opens a door to give the insight into the dynamic evolution of filaments in air.

Three-Dimensional Sound Propagation in the South China Sea with the Presence of Seamount
Journal of Marine Science and Engineering, 2021 Seamounts have important effects on sound propagation in deep water. A sound propagation experiment was conducted in the South China Sea in 2016. The three-dimensional (3D) effects of a seamount on sound propagation are observed in different propagation ...

Experimental Study on Optoelectronic Submarine Cable Used for Ship Radiation Noise Detection
IEEE AccessIn this study, we connected the DAS (distributed acoustic sensing) system to a 69-km optoelectronic submarine cable located in Hainan, China. A continuous four-day data collection was conducted to assess its potential for monitoring ship radiation noise.

Acoustic confinement and Stimulated Brillouin Scattering in integrated optical waveguides [PDF]
, 2013 We examine the effect of acoustic mode confinement on Stimulated Brillouin Scattering in optical waveguides that consist of a guiding core embedded in a solid substrate. We find that SBS can arise due to coupling to acoustic modes in three different regimes. First, the acoustic modes may be guided by total internal reflection; in this case the SBS gain

The Journal of the Acoustical Society of America, 2009 Acoustic metafluids are defined as the class of fluids that allow one domain of fluid to acoustically mimic another, as exemplified by acoustic cloaks. It is shown that the most general class of acoustic metafluids are materials with anisotropic inertia and the elastic properties of what are known as pentamode materials.
