    Metamaterial Can Change Optical Properties, Become Invisible or Reflective in IR Spectrum

    Article obtained from Photonics RSS Feed.

    Researchers at ITMO University and the University of Exeter have developed a metamaterial capable of changing its optical properties without any mechanical input. The new metamaterial could improve the reliability of complex optical devices while also making them cheaper to manufacture.

    Thanks to their complex periodical structure, metamaterials are relatively independent from the properties of their components. Such structures can be volumetric or flat, as is the case with metasurfaces.

    “Metasurfaces allow us to achieve many interesting effects in the manipulation of light,” ITMO researcher Ivan Sinev said. “But these metasurfaces have one issue: How they interact with light is decided right in the moment…
