For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays - without the need for artificially manufactured metamaterials. Scientists have long ...

Ether (or aether) is a term used in ancient mythology and medieval science to denote the matter that fills in the void of the universe. In the 19th century, physicists borrowed the concept to depict a ...

A material coating, whose light refraction properties can be precisely switched between different states, has been developed by an interdisciplinary research team from the Chemistry and Physics ...

If invisibility cloaks and other gee-whiz apps are ever to move from science fiction to science fact, we’ll need to know more about how these weird metamaterials actually work. Michigan Tech ...
