Metamaterials Perform 'Photonic Calculus'

Facebook X LinkedIn Email
The discovery that metamaterials can be designed to perform "photonic calculus" as lightwaves pass through them could give rebirth to analog computers. The theoretical metamaterial could perform a specific mathematical operation on a lightwave’s profile, such as finding its first or second derivative, as that lightwave passes through it, says a team from the University of Pennsylvania, University of Texas at Austin and University of Sannio. Computational metamaterials could almost instantly perform operations on the original wave, such as the light coming in through the lens...Read full article

    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
