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.

Surface acoustic waves in rotating orthorhombic crystals [PDF]
, 2012 The propagation of surface (Rayleigh) waves over a rotating orthorhombic crystal is studied. The crystal possesses three crystallographic axes, normal to the symmetry planes: the half-space is cut along a plane normal to one of these axes, the wave ...

Broadband reflected wavefronts manipulation using structured phase gradient metasurfaces
AIP Advances, 2016 Acoustic metasurface (AMS) is a good candidate to manipulate acoustic waves due to special acoustic performs that cannot be realized by traditional materials. In this paper, we design the AMS by using circular-holed cubic arrays.
