Research team develops acoustic topological insulator idea to allow for hiding from sonar
Landmark study proves that magnets can control heat and sound
Researchers at The Ohio State University have discovered how to control heat with a magnetic field.
Acoustic lens generates tunable 'sound bullets' for ultrasound applications
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 ...
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 ...
'Nano-earthquakes' hold key to smarter electronics
The performance of mobile phone cameras and solar cells could be boosted by "nano-earthquakes", researchers have found.
Researchers build acoustic tractor beam
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.
Ultracold Big Bang experiment successfully simulates evolution of early universe
(Phys.org) —Physicists have reproduced a pattern resembling the cosmic microwave background radiation in a laboratory simulation of the Big Bang, using ultracold cesium atoms in a vacuum chamber at the ...
Groundbreaking optical device could enhance optical information processing, computers
At St. Paul's Cathedral in London, a section of the dome called the Whispering Gallery makes a whisper audible from the other side of the dome as a result of the way sound waves travel around the curved surface. ...
New approach using nanoparticle alloys allows heat to be focused or reflected just like electromagnetic waves
An MIT researcher has developed a technique that provides a new way of manipulating heat, allowing it to be controlled much as light waves can be manipulated by lenses and mirrors.
Engineers make sound loud enough to bend light on a computer chip
During a thunderstorm, we all know that it is common to hear thunder after we see the lightning. That's because sound travels much slower (768 miles per hour) than light (670,000,000 miles per hour).
Electron spins controlled using sound waves
The ability to control the intrinsic angular momentum of individual electrons – their "spins" – could lead to a world of new technologies that involve storing and processing information.
