Experimental Realization of Acoustic Bianisotropic Gratings
Steven R. Craig, Xiaoshi Su, Andrew N. Norris +1
Acoustic bianisotropic materials couple pressure and local particle velocity fields to simultaneously excite monopole and dipole scattering, which results in asymmetric wave transm…
Retrieval method for the bianisotropic polarizability tensor of Willis acoustic scatterers
Xiaoshi Su, Andrew N. Norris
Acoustic materials displaying coupling between pressure and momentum are known as Willis materials. The simplest Willis materials are comprised of sub-wavelength scatterers that co…
Elastic metasurfaces for splitting SV- and P-waves in elastic solids
Xiaoshi Su, Zhaocheng Lu, Andrew N. Norris
Although recent advances have made it possible to manipulate electromagnetic and acoustic wavefronts with sub-wavelength metasurface slabs, the design of elastodynamic counterparts…
Broadband focusing of underwater sound using a transparent pentamode lens
Xiaoshi Su, Andrew N. Norris, Colby W. Cushing +2
We report an inhomogeneous acoustic metamaterial lens based on spatial variation of refractive index for broadband focusing of underwater sound. The index gradient follows a modifi…
Enhanced acoustic transmission through a slanted grating
Andrew N. Norris, Xiaoshi Su
It is known that an acoustic wave incident on an infinite array of aligned rectangular blocks of a different acoustic material exhibits total transmission if certain conditions are…
