Experimental validation of deep-subwavelength diffusion by acoustic metadiffusers

HIGHLIGHTS

  • who: . and collaborators from the United Kingdom have published the research work: Experimental validation of deep-subwavelength diffusion by acoustic metadiffusers, in the Journal: (JOURNAL) of 11/05/2019
  • what: The aim of this work is to experimentally validate the concept of metadiffusers from the scattering measurements of a specific metadiffuser design i.e. a Quadratic Residue Metadiffuser (QRM). The authors show for the first time the experimental validation of the concept of acoustic metadiffusers. In this work, the response was evaluated at 2000 Hz to avoid the strong diffractive regime of the finite panel . . .
