Metamaterials Negative Refraction

Caption

The shape and positioning of the rods in this metamaterial cause light--the arrow--to bend at a negative angle, a process called negative refraction. Better understanding of this dynamic will speed the development of new metamaterials such as perfect lenses and invisibility cloaks, says Michigan Tech's Elena Semouchkina.
