    It looks like there's a way to go before this applies to photography... a looooong way.

    From the article: "This does not mean the energy velocity of light passing through this material goes to infinity, or faster than the speed of light through air," Yang told us. "It's only the phase velocity of light that reaches infinity."

    And:"Typically, optical devices used for image processing, energy redirecting, and communications rely on only a single wavelength or frequency to transmit light. The new material's broadband capability mans that the meta-atoms could be used as building blocks in new types of optical components that operate over a range of frequencies. For example, it could be used to direct a laser to certain orientations or angles, such as in surgery, said Yang. Laser energy redirecting can also be used to increase an image's resolution. In optical communications, a broadband waveguide could be built with increased bandwidth."

    I agree, it could be weeks, maybe months before they find a use for it. At the rate technology is advancing you can never be sure.:smile:
