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 ...

another way to characterize the wave is by the number of waves received per second. This is the frequency of the wave. Morrison and Cocconi considered how well the types of electromagnetic waves ...

Researchers interrogated the 'sounds' of a cluster of stars within the Milky Way, uncovering a new technique for astrophysicists to probe the universe and learn more about its evolution.

“Metasurfaces are engineered materials that manipulate wave behaviour in ways that natural materials cannot,” said Zhong. “In ...

Audible enclaves are small pockets of sound that are not disturbed by surrounding noise. They are produced by new ...

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.
