Acoustic Wavefront Shaping Using Ultrahigh Phase Resolution Metamaterial

open access: yesAdvanced Materials Technologies, EarlyView.
A Bilateral Symmetrical T‐shaped (BST) acoustic metamaterial unit cell capable of achieving a high phase resolution of π/36 radians at 8000 Hz is introduced. The approach enables tunable wavefront control through simple rotational adjustment of BST, which offers an alternative to the conventional complex metamaterials unit cell design and a way for ...
