Abstract
An underwater acoustic metasurface for wide-angle and efficient focusing in transmission mode is designed. Numerical results show that the metasurface can focus oblique-incident waves up to 45° at the same power level as the normal-incident case. The metasurface also exhibits good achromatic capability with a large spatial incident angle view.
