A Parametric Study of the Acoustic Mechanism for Core-Collapse Supernovae [PDF]
, 2017 We investigate the criterion for the acoustic mechanism to work successfully in core-collapse supernovae. The acoustic mechanism is an alternative to the neutrino-heating mechanism.

Ion acoustic traveling waves [PDF]
Journal of Plasma Physics, 2014 AbstractModels for traveling waves in multi-fluid plasmas give essential insight into fully nonlinear wave structures in plasmas, not readily available from either numerical simulations or from weakly nonlinear wave theories. We illustrate these ideas using one of the simplest models of an electron–proton multi-fluid plasma for the case where there is ...

Research Progress of Locally Resonance Acoustic Metamaterials [PDF]
E3S Web of Conferences, 2021 Bragg scattering phonon crystal and locally resonant acoustic metamaterials were introduced. In order to generate noise reduction, the lattice constant of Bragg scattering phonon crystal should be of the same order of magnitude as the wave length of the ...

Raman gain against a background of non-thermal ion fluctuations in a plasma [PDF]
, 2000 A complex stimulated Raman scattering event against a background of non-thermal ion acoustic waves in an inhomogeneous plasma is described. We obtain analytic forms for the Raman gain due to a five-wave interaction consisting of conventional three-wave ...

Relativistic Acoustic Geometry [PDF]
, 1999 Sound wave propagation in a relativistic perfect fluid with a non-homogeneous isentropic flow is studied in terms of acoustic geometry. The sound wave equation turns out to be equivalent to the equation of motion for a massless scalar field propagating ...

General Synthesis Methodology for the Design of Acoustic Wave Ladder Filters and Duplexers
IEEE Access, 2018 In a scenario where the segment of wireless communication systems are allocated in an ever more crowded frequency spectrum, the design of filtering structures, stand-alone, duplexers, or multiplexers, become a challenging task. Moreover, filters based on

Surface Acoustic Wave (SAW) for Chemical Sensing Applications of Recognition Layers †
Italian National Conference on Sensors, 2017 Surface acoustic wave (SAW) resonators represent some of the most prominent acoustic devices for chemical sensing applications. As their frequency ranges from several hundred MHz to GHz, therefore they can record remarkably diminutive frequency shifts ...
