Metamaterials

Metamaterials are engineered structures designed to interact with electromagnetic radiation in a desired fashion. They usually comprise an array of structures smaller than the wavelength of interest. These so-called meta-atoms can interact with the electric and magnetic components of light in a way that natural atoms do not.

    Colloidal nanocrystals can form into periodic superlattices exhibiting collective vibrations from the correlated motion of the nanocrystals. This Perspective discusses such collective vibrations and their as-of-yet untapped potential applications for phononic crystals, acoustic metamaterials and optomechanical systems.
