Don't put a down payment on that invisible plane just yet but a team of scientists from Boston College and Duke University developed a highly-engineered metamaterial capable of absorbing all of the light that strikes it – to a scientific standard of perfection.

The metamaterial uses tiny geometric surface features to successfully capture the electric and magnetic properties of a microwave to the point of total absorption.

The group used computer simulations based on prior research findings in the field to design resonators able to couple individually to electric and magnetic fields to successfully absorb all incident radiation, according to the findings in Physical Review Letters..

Because its elements can separately absorb the electric and magnetic components of an electromagnetic wave, the "perfect metamaterial absorber" created by the researchers can be highly absorptive over a narrow frequency range.

The metamaterial is the first to demonstrate perfect absorption and unlike conventional absorbers it is constructed solely out of metallic elements, giving the material greater flexibility for applications related to the collection and detection of light, such as imaging, says Padilla, an assistant professor of Physics.

Metamaterial designs give them new properties beyond the limits of their actual physical components and allow them to produce "tailored" responses to radiation. Because their construction makes them geometrically scalable, metamaterials are able to operate across a significant portion of the electromagnetic spectrum.

"Three things can happen to light when it hits a material," says Boston College Physicist Willie J. Padilla. "It can be reflected, as in a mirror. It can be transmitted, as with window glass. Or it can be absorbed and turned into heat. This metamaterial has been engineered to ensure that all light is neither reflected nor transmitted, but is turned completely into heat and absorbed. It shows we can design a metamaterial so that at a specific frequency it can absorb all of the photons that fall onto its surface."

In addition to Padilla, the team included BC researcher Nathan I. Landy, Duke University Professor David R. Smith and researchers Soji Sajuyigbe and Jack J. Mock.
