Acoustic Macroscopic Rigid Body Levitation by Responsive Boundary Hologram
Seki Inoue, Shinichi Mogami, Tomohiro Ichiyama +3
Propagated acoustic waves, which generate radiation pressure, exert a non-contact force on a remote object. By suitably designing the wave field, remote tweezers are produced that…

Electronically Steerable Ultrasound-Driven Air Stream
Keisuke Hasegawa, Liwei Qiu, Akihito Noda +2
We have created a stretching air flow by generating a Bessel beam of ultrasound with an active phased array of acoustic transducers in free space. The generated Bessel beam is elec…
