Scientists at Cornell University have created a new metamaterial that is considered to be “darker than black”. Black typically absorbs about 85 percent of incoming light, but this new material is claimed to absorb a stunning 99 percent. The researchers said that they used arrays of silver nanowires grown in alumina membranes to come up with a hyperbolic metamaterial. To decrease light reflection, they ground the surface to create corrugations and defects.
