Metamaterials

A metamaterial is a material engineered to have a property that is not found in nature. They are made from assemblies of multiple elements fashioned from . Metamaterial cloaking is the usage of metamaterials in an invisibility cloak.

This is accomplished by manipulating the paths traversed by light through a novel . After another news story about a “Harry Potter invisibility cloak”, we take a look at the science behind metamaterials. Metamaterials are materials whose electromagnetic or acoustic properties arise. A team led by Cory Dean, assistant professor of physics at Columbia University, Avik Ghosh, professor of electrical and computer engineering at the University of .

Discover the technology behind metamaterials. Learn how we arrange conventional metals or plastics into periodic patterns to create smart materials. Metamaterials: A Definition - Metamaterials are artificially structured materials used to control and manipulate light, soun and many other physical phenomena.
