  2. Invisible cloaks and the perfect lens

    16 May 2011 | | Contributor(s):: John Pendry

    Refractive materials gives us some limited control of light: we can fashion lenses, and construct waveguides, but complete control of light is beyond simple refracting materials. Ideally we might wish to channel and direct light as we please just as we might divert the flow of a fluid....

  3. Metamaterials, Part 2: Negative-Index, Nonlinear Optics and Super/Hyper-Lenses

    01 May 2008 | | Contributor(s):: Vladimir M. Shalaev

    Part 2/3. Metamaterials are expected to open a gateway to unprecedented electromagnetic properties and functionality unattainable from naturally occurring materials, thus enabling a family of new “meta-devices”. In these three lectures, we review this new emerging field and significant progress...
