<a href="http://www.engadget.com/tag/metamaterials/">Metamaterials</a> are proving to be quite useful for toying with the electromagnetic spectrum, whether for technology previously thought to be the stuff of <a href="http://www.engadget.com/2012/11/12/duke-university-creates-perfect-one-directional-microwave-cloak/">science fiction</a>, or for boring <a href="http://www.engadget.com/2012/08/21/intellectual-ventures-launches-kymeta-satellite-broadband-spinoff/">real-world applications</a>. Engineers at <a href="http://www.engadget.com/tag/dukeuniversity">Duke University</a> have come up something that falls more into the latter category: a metamaterial imaging sensor that doesn't require a lens to generate a picture. The sensor is a flexible copper-plated sheet patterned with small squares that capture various light frequencies all at once, functioning like one big aperture.
