Metamaterial Puzzle Solved

Facebook X LinkedIn Email
NORFOLK, Va., and CORVALLIS, Ore., Dec. 16, 2008 -- Researchers have solved one of the significant remaining challenges with photonic “metamaterials,” discovering a way to prevent the loss of light as it passes through these materials, and opening the door to many important new optical, electronic and communication technologies. “This is a significant breakthrough,” said Mikhail Noginov, professor in the department of physics and the Center for Materials Research at Norfolk State University in Norfolk, Va. The advance was made by Noginov and other scientists at Norfolk State, working with Viktor Podolskiy, an assistant professor of physics...Read full article

    Glossary
    adsorption
    The process by which a substance, usually a solid, attracts and retains on its surface the molecules of another substance.
    dielectric
    Exhibiting the characteristic of materials that are electrical insulators or in which an electric field can be sustained with a minimum dispersion of power. They exhibit nonlinear properties, such as anisotropy of conductivity or polarization, or saturation phenomena.
    electronics
    That branch of science involved in the study and utilization of the motion, emissions and behaviors of currents of electrical energy flowing through gases, vacuums, semiconductors and conductors, not to be confused with electrics, which deals primarily with the conduction of large currents of electricity through metals.
    light
    Electromagnetic radiation detectable by the eye, ranging in wavelength from about 400 to 750 nm. In photonic applications light can be considered to cover the nonvisible portion of the spectrum which includes the ultraviolet and the infrared.
    machine vision
    Machine vision, also known as computer vision or computer sight, refers to the technology that enables machines, typically computers, to interpret and understand visual information from the world, much like the human visual system. It involves the development and application of algorithms and systems that allow machines to acquire, process, analyze, and make decisions based on visual data. Key aspects of machine vision include: Image acquisition: Machine vision systems use various...
    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...
    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...
