Simple acoustic metagrating for perfect two- and three-beam splitting
Acoustic metasurfaces have been widely explored and attracted great attention for their extraordinary wavefront manipulation abilities. In this paper, we propose a simple acoustic metagrating with periodic grooves that can split a normally incident beam into two or three reflected beams. The amplitu...
