Metamaterial 'Flat Lens'
    
  A NIST team created an ultraviolet (UV) metamaterial formed of alternating nanolayers of silver (green) and titanium dioxide (blue).  When illuminated with UV light (purple) a sample object of any shape placed on the flat slab of metamaterial is projected as a three-dimensional image in free space on the other side of the slab.  Here a ring-shaped opening in an opaque sheet on the left of the slab is replicated in light on the right.
