Engineers build first nonreciprocal acoustic circulator: A one-way sound device
A team of researchers at The University of Texas at Austin's Cockrell School of Engineering has built the first-ever circulator for sound. The team's experiments successfully prove that the fundamental symmetry ...
World's first 3-D acoustic cloaking device hides objects from sound
(Phys.org) —Using little more than a few perforated sheets of plastic and a staggering amount of number crunching, Duke engineers have demonstrated the world's first three-dimensional acoustic cloak. The ...
Fantastic phonons: Blocking sound, channeling heat with 'unprecedented precision'
Imagine living on a bustling city block, but free from the noise of car horns and people on the street. The emerging field of phononics could one day make this a reality.
Researchers build acoustic tractor beam
The world's smallest microlaser
ETH-Zurich physicists (Switzerland) have developed a new kind of laser that shatters the boundaries of possibility: it is by far the smallest electrically pumped laser in the world and one day could revolutionize ...
How to prevent earthquake damage: make buildings invisible
Acoustic lens generates tunable 'sound bullets' for ultrasound applications
Designing an acoustic diode
Most people know about ultrasound through its role in prenatal imaging: those grainy, grey outlines of junior constructed from reflected sound waves. A new technology called an "acoustic diode," envisioned ...
Surfing on acoustic waves (w/ Video)
(Phys.org) —ETH researchers are able to make objects such as particles and liquid droplets fly in mid-air by letting them ride on acoustic waves. For the first time, they have been able to also control ...
Sound bullets could treat cancers and replace ultrasound (w/ Video)
Researchers use artificially engineered materials to create breakthrough for sound sensors
University of Maryland (UMD) A. James Clark School of Engineering researchers have developed breakthrough technology to improve sound sensor capabilities through the use of artificially engineered materials.
NASA spacecraft records 'Earthsong'
Nobody ever said anything about singing, though. A NASA spacecraft has just beamed back a beautiful song sung by our own planet.
Physicists split and collide ultracold atom clouds (w/ Video)
Physicists at New Zealand's University of Otago have pushed the frontiers of quantum technology by developing a steerable 'optical tweezers' unit that uses intense laser beams to precisely split minute clouds ...
New technique allows ultrasound to penetrate bone, metal
Researchers from North Carolina State University have developed a technique that allows ultrasound to penetrate bone or metal, using customized structures that offset the distortion usually caused by these ...
