This image is a simulation of a kind of acoustic wave called a Rayleigh-Bloch wave. The stripes of light and dark areas represent the “peaks" and “troughs" of the waves and are shaped by their ...

This will vastly improve the ability to rapidly design metamaterials – exciting artificial materials used to amplify, block or deflect waves. The findings, published in the journal Proceedings of the ...

In a new Physical Review Letters study, researchers have successfully followed a gravitational wave's complete journey from the infinite past to the infinite future as it encounters a black hole.
