Metamaterials can be used to create invisibility cloaks and change how light reacts with a blanket of special elements. How were engineers able to make them? Trace explains.
Squeezing Light into Metals
“Using an inexpensive inkjet printer, University of Utah electrical engineers produced microscopic structures that use light in metals to carry information.”
Terahertz Plasmonic Structures Based on Spatially Varying Conductivities
“Terahertz plasmonic structures are demonstrated in which the conductivity of the metallic film is varied spatially in order to further enhance the response.”
“Plasmonics is the study of the interaction between electromagnetic field and free electrons in a metal.”
“In physics, a plasmon is a quantum of plasma oscillation.”
Ultra-high-strength metamaterial developed using graphene
“New metamaterial has been developed exhibiting hundreds of times greater strength than pure metals.”
Is the army testing an invisible tank?
“Researchers are currently exploring the possibilities associated with an artificial type of matter called metamaterials.”
