Acoustic metamaterial and homogenization theory in sound blocking applications

, 2012
Acoustic metamaterials have novel properties in propagating sonic waves for its artificially structured inclusions. As one of those unconventional features, the evanescent forms of inside waves, which breaks mass-density law for traditional material ...

Active acoustical metamaterials

, 2014
En accord avec l'équation de propagation des ondes élastiques dans la matière, l'expression de la vitesse du son n'interdit pas à la masse volumique et à la compressibilité effectives du milieu d'être toutes deux négatives. Comment concevoir alors un tel matériau qualifié de métamatériau acoustique ? Qu'elles sont ses principales propriétés ?
