Acoustic metamaterials offer a new paradigm for the control and manipulation of sound waves that are often unachievable through conventional materials. The potential this offers to the field of sound absorption, insulation, cloaking, and imaging are remarkable. Acoustic metamaterials also allow material ...

1. Introduction Metamaterials are effective media made of periodic (or quasiperiodic) inclusions of conventional materials (typically metals and dielectrics) with controllable acoustic, electromagnetic, or optical properties. Indeed, by properly structuring these artificial materials, it is possible to ...
During the past decade, materials that display novel properties in the acoustic realm, so-called acoustic metamaterials, have attracted much attention, since these properties can provide promising opportunities to design new acoustic devices that cannot be made with natural materials. Although acoustic me...
with the development of acoustic metamaterials with unusual acoustic parameters (for example, negative refractive index)106,107,108, integrating these materials into microfluidic devices can manipulate and control sound waves in ways that are not possible in conventional materials, which can further improv...
Physics of metamaterials When a wave is incident on a material, the change in its electromagnetic response is governed by the two fundamental parameters i.e. permittivity (ε) and permeability (μ). These material properties are, in general, unique for every material owing to their distinctive ...
They have been also used to manipulate elastic waves, but such waves have a coupling property, so metamaterials for elastic waves uses a different method than for electromagnetic and acoustic waves. Since researches on this type of metamaterials is sparse, this paper reviews studies that used ...
New nanomaterials used in nano-biosensing technologies are among the most interesting sensing materials owing to their unique size and shape-dependent optical properties, high surface energy, large surface-to-volume ratio, and tunable surface properties. Such materials exhibit excellent reactivity, spectral...
