Invisibility cloaks closer thanks to 'digital metamaterials'
The concept of "digital metamaterials" – a simple way of designing metamaterials with bizarre optical properties that could hasten the development of devices such as invisibility cloaks and superlenses – is reported in a paper published today in Nature ...
Layered graphene sandwich for next generation electronics
Sandwiching layers of graphene with white graphene could produce designer materials capable of creating high-frequency electronic devices, University of Manchester scientists have found.
Consider the 'anticrystal'
(Phys.org) —For the last century, the concept of crystals has been a mainstay of solid-state physics. Crystals are paragons of order; crystalline materials are defined by the repeating patterns their constituent ...
