Mathematicians and engineers at the University of Utah have teamed up to show how ultrasound waves can organize carbon particles in water into a sort of pattern that never repeats. The results, they ...
ANC does not shut the world out. It listens to outside noise, flips the sound pattern, and makes certain sounds feel weaker ...
Patterned elastic plate guides ultrasonic waves and traps different frequencies at separate bulk locations, enabling compact ...
Yushun Zeng squishes cancer cells in a petri dish at work. No, not with his ungainly, macroscopic human fingers. Zeng, an engineering graduate student at the University of Southern California, has ...
The top layer represents the location of the sound source and the path of sound propagation (A). The bottom layers represent convergence zones with different sound propagation paths (B-F). Sound waves ...

Wafer-thin silicon with millions of patterns redirects vibrations along predefined paths
Metamaterials—the term may sound esoteric to the layman. In science and engineering, however, this is an interesting field of research that has developed at a highly dynamic pace, particularly since ...
