Highly efficient transmissive wavefront steering with acoustic metagrating composed of Helmholtz-resonators
Recently, a kind simply structured metasurface made of binary phase modulated meta-unit shows extraordinary beam steering functionality especially in the reflective beam manipulation. In this work, we demonstrate a Helmholtz-resonator based acoustic metagrating for high efficient beam wavefront stee...
