Metamaterial Manipulates Light at Will

Facebook X LinkedIn Email
DURHAM, N.C., Aug. 2, 2011 — Much in the same way that electronics manipulate electrons, Duke University researchers have developed a material that allows them to manipulate light at will, a discovery that could help replace electronic components with optical technology. Light-based devices would enable faster and more efficient transmission of information, similar to how optical fibers revolutionized the telecommunications industry by replacing wires.

    metamaterial
    Metamaterials are artificial materials engineered to have properties not found in naturally occurring substances. These materials are designed to manipulate electromagnetic waves in ways that are not possible with conventional materials. Metamaterials typically consist of structures or elements that are smaller than the wavelength of the waves they interact with. Key characteristics of metamaterials include: Negative refraction index: One of the most notable features of certain...
