description abstractThe phenomenon of near-field concentration of sound wave plays an important role in harnessing of sound wave in underwater sonar or similar devices, where high pressure field is required. Material parameters for the metamaterial-assisted acoustic concentrators with arbitrary N-sided regular polygonal cross section are derived based on coordination transformation approach. Acoustic intensity enhancement of the concentrator has been shown by full-wave simulation. All theoretical and numerical results validate the generality and effectiveness of the proposed designing method.
