Acoustic metamaterials can manipulate and control sound waves in ways that are not possible in conventional materials. Metamaterials with zero, or even negative, refractive index for sound offer ...

Light can behave in very unexpected ways when you squeeze it into small spaces. In a paper in the journal Science, Mark ...

Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could also be used in technical applications with electromagnetic waves.

Sound waves as a toy model Over several years, the ETH researchers developed and theoretically modeled the various parts of the circulator; now, finally, they could experimentally demonstrate that ...

Sound stored in the first resonator can leak into the second, but not vice versa.” Harris said his team was able to achieve the result with a “tuning knob” — a laser setting, actually — that can ...

Ascending scale: sound waves rise as they travel through media. (Courtesy: Shutterstock/Appler) A new theoretical study has revealed how sound waves transfer small amounts of mass as they travel.

Sound waves can shrink fat Japanese researchers discovered that specific sound frequencies (440 Hz and 14 kHz) can alter gene expression in mice cells, inhibiting fat cell differentiation and ...
