      Engineers devise invisibility shield
      Philip Ball

      Electron effects could stop objects from scattering light.

      The idea of a cloak of invisibility that hides objects from view
      has long been confined to the more improbable reaches of science
      fiction. But electronic engineers have now come up with a way to
      make one.

      Andrea Al├╣ and Nader Engheta of the University of Pennsylvania in
      Philadelphia say that a 'plasmonic cover' could render objects
      "nearly invisible to an observer". Their idea remains just a
      proposal at this stage, but it doesn't obviously violate any laws
      of physics.

      "The concept is an interesting one, with several important
      potential applications," says John Pendry, a physicist at
      Imperial College in London, UK. "It could find uses in stealth
      technology and camouflage."
