In recent years, an increasing number of pioneering studies have been carried out in the field of acoustic metamaterials, following the path of electromagnetic metamaterials. These artificial engineered materials are designed in such a way so as to achieve ...

The optical dispersive prism is a well-studied element, which allows separating white light into its constituent spectral colors, and stands in nature as water droplets. In analogy to this definition, the acoustic dispersive prism should be an acoustic dev ...

It has been shown that acoustic waves with helical wavefronts can carry angular momentum, which can be transmitted towards a propagating medium. Such a wave field can be achieved by using a planar array of electroacoustic transducers, forming a given spati ...

In this article we make an analogy between Electromagnetic and Acoustic transmission-line modelling. Then we use this to introduce acoustic transmission-line metamaterials and finally we introduce the acoustic leaky-wave antenna on the basis of previous st ...

Recent studies have focused on developing metamaterials for acoustic applications, inspired by electromagnetics concepts. The acoustic leaky-wave antenna is amongst the most investigated. Despite the unfavourable properties of conventional matter and struc ...

Metasurfaces have gained fame for their ability to control the transmitted and reflected phase front of waves. Here, we introduce a reflector-type acoustic metasurface designed in such a way to control the phase front of reflected sound waves. The proposed ...

In the last years, the number of studies carried out in the field of acoustic metamaterials has significantly increased. In year 2009, our group proposed a concept of acoustic composite right/left hand transmission line (CRLH-TL) metamaterial, consisting o ...

Funneling acoustic waves through largely mismatched channels is of fundamental importance to tailor and transmit sound for a variety of applications. In electromagnetics, zero-permittivity metamaterials have been used to enhance the coupling of energy in a ...

Acoustic metasurfaces have gained popularity for their capability to tailor the phase front of transmitted and reflected waves. While most of researches conducted in this topic are spinning around different applications and peculiar physics of these surfac ...

Les métamatériaux acoustiques désignent des structures acoustiques présentant des propriétés inédites dans la nature, comme une masse négative et/ou un module de compressibilité négatif. Une réalisation de type ligne de transmission unidimensionnelle, cons ...
