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…
