Scientists get closer to creating invisibility cloak

Scientists at Duke University are reportedly one step closer to creating the invisibility cloak we’ve all been dreaming of. David R. Smith, a professor of electrical and computer engineering at Duke says “The new device can cloak a much wider spectrum of waves–nearly limitless–and will scale far more easily to infrared and visible light. The approach we used should help us expand and improve our abilities to cloak different types of waves.”  The current cloak prototype measures 20-inches by 4-inches and is less than an inch high. Scientist say it took nine days to take the device from conception to fabrication, a huge improvement in speed from the four months it took to create the original device. [via CNET]
