Zhang’s metamaterial features a small sawtooth pattern on its surface, which allows adjacent speakers to exert different forces on the material based on how the sound waves reflect off it.

Zhang designed a metamaterial featuring a small sawtooth pattern. This pattern alters how sound waves reflect when multiple speakers target it from different angles. The result: controlled motion.

Sound waves do far more than carry music or voices. In science and engineering, they help map the seafloor, monitor earthquakes, guide submarines, and even shatter kidney stones inside the human body.

Researchers from University of Wisconsin-Madison have unveiled a new acoustic metamaterial capable of moving and rotating ...

In Zhang’s case, he structured his metamaterial with a sawtooth-patterned surface. The novel surface allows sound waves to exert different forces on the material due to how they divergently reflect ...

Brian Wilson’s 1966 masterpiece is now considered a crowning achievement of music. The album’s reputation grew over time.

The wildest trampoline in the world swings sideways and "around corners." Yet, no one can jump on it, because it's not even a ...

A plastic structure separates white noise into pitches, like a rainbow splits light into colors, offering a novel way to manipulate sound.

Earthquakes create ripple effects in Earth's upper atmosphere that can disrupt satellite communications and navigation systems we rely on. Scientists have now used Japan's extensive network of Global ...
