Acoustic Metasurface

Metasurfaces have gained fame for their ability to control the transmitted and reflected phase front of waves. Here, we introduce a reflector-type acoustic metasurface designed in such a way to control the phase front of reflected sound waves. The proposed structure can be considered an acoustic counterpart of the electromagnetic reflectarray antenna. This structure is very thin (lambda=30), and possesses sub-wavelength unit-cells.
