   Abstract:
   A fundamental limit for GSL-based metasurfaces is their power efficiency, especially at large deflection angles. Here we designed and fabricated the bi-anisotropic cells for wavefront transformation acoustic metasurface that overcomes this limit, allowing us to steer the power flow without parasitic scattering. Our discretized design is verified numerically and experimentally.
