Polymeric composites with multi-functionality offer significant advantages over metals,
including lightweight, high strength and stiffness, corrosion and fatigue resistance, etc …

The effective operation of certain electronic, medical, industrial, and testing equipment relies
on high-quality focusing and imaging capability, which also plays a vital role in the field of …

Metasurfaces are planar metamaterials with a flat surface and a subwavelength thickness
that are able to shape arbitrary wave fronts such as focusing or imaging. There is a broad …

Superlenses, hyperlenses, and metalenses can achieve a resolution beyond that permitted
by diffraction, advancing the development of elastic wave imaging. However, a …

In this paper, elastic wave dispersion characteristics of two novel unit-cells are numerically
and experimentally studied. Based on Bloch's theorem for infinite cellular structures, the …

Metaplates, ie 2D extruded structures made by a periodic repetition of unit cells that exhibit a
complete and wide 3D bandgap, are attracting increasing interest thanks to the variety of …

Tunable acoustic wave design is essential in phononic crystals (PnCs) because acoustic
waves constantly change in various frequency ranges during practical applications. In this …

An elastic metasurface is an artificial structure composed of subwavelength structures that
can manipulate elastic waves with an arbitrary phase gradient transformation. However …

We propose an acoustic-mechanical metasurface with simultaneous sound absorption and
vibration reduction functionalities. This acoustic-mechanical feature results from a nonlocal …

Controlling and manipulating elastic/acoustic waves via artificially structured metamaterials,
phononic crystals, and metasurfaces have gained an increasing research interest in the last …
