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.
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 ...
Acoustic lens generates tunable 'sound bullets' for ultrasound applications
How to prevent earthquake damage: make buildings invisible
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 build acoustic tractor beam
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 ...
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 ...
Sound could save circuits: Researchers theorize acoustic waves may cool microelectronics
(PhysOrg.com) -- "Hot sounds" has one meaning to music fans and another to physicists. Count a team of researchers at Rice University among the latter, as they've discovered that acoustic waves traveling along ...
Radiation damage bigger problem in microelectronics than previously thought
The amount of structural damage that radiation causes in electronic materials at the atomic level may be at least ten times greater than previously thought.
