The term metamaterials for such substances was suggested by Roger Walser in 1999. But only in the early 2000s have researchers figured out how to create materials of any type that can achieve negative ...

Their tests confirmed that the material’s energy storage capacity, or enthalpy, is between 2 and 160 times greater than other ...

Metamaterials are artificially-structured materials ... A Perspective is a peer-reviewed content type that the journal uses to invite reflection or discussion on matters that may be speculative ...

An international research team has developed mechanical metamaterials with a high elastic energy density. Highly twisted rods that deform helically provide these metamaterials with a high stiffness ...
