Metamaterials are artificial composite materials composed of at least two different materials. They possess a large number of ...

Metamaterials are engineered to exhibit unusual properties, such as band gaps that block mechanical vibrations of certain frequencies. While these properties can be tuned, adjusting and maintaining a ...

A new metamaterial silencer inspired by noise-canceling headphones offers dynamic sound control for offices, factories, and public spaces.

The Zhang lab has since extended its work to explore a broader range of acoustic silencing strategies—including multi-band, ...
