"MATERIALS: Metamaterials to enable 3-D displays"

Metamaterials use composite resonators that can bend light any which way, potentially cloaking regions of space from visibility by diverting light around them. Now a mathematician has offered a blueprint for casting metamaterials into hollow fibers to create cloaked tunnels, each of which masks the light ascending from a planar pixel array to illuminate a 3-D display. By arraying the tiny cloaking tunnels in 3-D, light from the planar pixel array would travel up through the fibers unobserved except for their glowing ends, which would appear to be floating in space.
