Community News - Nanotransfer printing for metamaterials

Posted on April 22, 2014

Researchers at the University of Central Florida have published research describing the use of nanotransfer printing in creating large-scale negative-index 3D metamaterials for the visible light range. Alternating layers of silver and dielectrics create a fishnet-like pattern that can be designed to create a negative refractive index material. They were able to produce a sammple with an area of four square centimetres - this may seem small, rather than large, but previous visible light metamaterials were limited to the micron scale.
