Molecular dynamics study on size-dependent elastic properties of silicon nanocantilevers
TL;DR: In this article, the motion of nanoscale structures made of pure crystalline silicon with different lattice conditions is simulated in vacuum by applying the molecular dynamics technique with the use of the Tersoff potential.

Sound energy harvesting using a doubly coiled-up acoustic metamaterial cavity
TL;DR: In this article, an acoustic metastructure and a double-clamped piezoelectric bimorph plate were designed by utilizing a doubly coiled-up configuration for strong confinement of the sound energy inside the acoustic metamaterial cavity in the low frequency range.

Emission Enhancement of Sound Emitters using an Acoustic Metamaterial Cavity
TL;DR: periodic zigzag elements which exhibit Fabry-Perot resonant behavior below the phononic band-gap are used to yield strong sound localization within the subwavelength gap, thus providing highly effective emission enhancement.
Directional Reflective Surface Formed via Gradient-Impeding Acoustic Meta-Surfaces
TL;DR: This work reports on a new type of directional reflective surface consisting of an array of sub-wavelength Helmholtz resonators with varying internal coiled path lengths, which induce a reflection phase gradient along a planar acoustic meta-surface.
Sound pressure level gain in an acoustic metamaterial cavity.
TL;DR: An acoustic metamaterial localization cavity which is used for sound pressure level (SPL) gain using double coiled up space like structures thereby increasing the range of detection and experimentally verifying the SPL amplification in an underwater environment at higher frequencies.
