Steering flexural waves in thin plates benefits several applications, including vibration
energy harvesting and micro-electro-mechanical systems (MEMS). This study proposes a …

Aiming to attenuate very low-frequency flexural wave in a thin plate, this paper proposes a
meta-plate model by periodically attaching high-static-low-dynamic-stiffness (HSLDS) …

We report a novel approach to control flexural waves in thin plates using metasurfaces
constituted of an array of parallel arranged composite beams with their neutral planes the …

The ability to acoustically cloak an object, effectively making the object acoustically invisible
to an outside observer, is of interest in many applications where the presence of an object …

Increasing the service-life of engineering structures such as aeroplanes is a major issue in
order to enhance their cost-effectiveness and to reduce the carbon footprint. One possibility …

This paper deals with the band structures of thermoelastic waves in nano-scale phononic
crystal or metamaterial beams considering nano-size effects. The nonlocal coupled …

Active noise cloaking of rigid and elastic 2D cylindrical shells in an infinite acoustic medium
is presented. The control approach utilises control sources or forces and discrete error …

Out-of-plane flexural and in-plane extensional motions are independently analyzed in
available studies of multiple scattering due to the assumption of the consistent mid-plane …

We report a novel approach to control the wavefronts of shear vertical (SV) waves in solids
using metasurfaces constituted by a stacked array of composite plates, which are composed …

The study of artificially structured materials to control waves is ongoing, owing to their
unprecedented properties. However, their narrow working frequency ranges significantly …
