A new paper explains how signals oscillating at complex-valued frequencies could transform sensing, imaging, and ...

By combining ultrasound with a concept called nonlinear acoustics, you can create sound that stays silent until it reaches a ...

The sound quality is not just bad, it’s abysmal. It sounds like, as per my headline, the most talented musicians are doing ...

Researchers report their insights on the emerging field of complex frequencies excitations, a recently introduced scheme to control light, sound and other wave phenomena beyond conventional limits.

A group of international researchers have developed a way to use sound to generate different types of wave patterns on the ...

Different materials and molecules inside the tissue absorb different amounts of the incident light at different wavelengths, creating individual "fingerprints" in the emitted sound waves.

When the tissue absorbs the light, it heats up slightly - by less than 1 degree Celsius - causing it to expand and contract. This tiny movement generates ultrasonic sound waves, which can be detected ...

However, by using acoustic metasurfaces—specialized materials that manipulate sound waves—we can shape ultrasound beams to bend as they travel. Similar to how an optical lens bends light, acoustic ...
