Acoustic water display.

ABSTRACT: Cross-boundary communication between media with high impedance mismatch, such as air and water, remains a major challenge for conventional wireless transmission systems. At such interfaces, most of the emitted signal energy is reflected at the media boundaries. Here, we propose a novel display technology for optical information transmission across such an interface, using acoustic radiation pressure to dynamically shape the water-air boundary. The design is based on the combination of spatiotemporal deformations of a water-air interface induced by acoustic radiation pressure. It allows to shape a water-air interface in real-time. By tuning an incident acoustic field at the interface, we demonstrate the ability to generate contactless complex deformation shapes, such as ellipsoidal deformat
