Flexible Smart Material Cloaks Objects

Facebook X LinkedIn Email
FIFE, Scotland, Nov. 5, 2010 — Using tiny atoms that can interact with light, researchers at the University of St. Andrews have developed a flexible new ‘smart’ material that could theoretically appear invisible to the naked eye. It is the first practical breakthrough in the much-theorized area of physics – invisibility cloaking. Metaflex membrane placed on a disposable contact lens and illuminated with office light. The inset is an enlargement of the membrane. Although cloaks designed to shield objects from both terahertz and near infrared waves have already been designed, a flexible...Read full article

    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...
