Stealth aircraft like the F-35 are built to go slower than older aircraft, so it doesn't emit as much of a heat signature.

Finally, the Shalaev and Smolyaninov groups have recently demonstrated broadband cloaking in a specially tapered waveguide, which emulates well the metamaterial-based anisotropic cloak and thus ...

How metamaterials bend the paths of electromagnetic radiation (i.e. refraction) drives their peculiar applications. For example, a metamaterial invisibility cloak would bend the paths of light waves ...

An origami-inspired ‘metamaterial’ has been engineered to have properties not found in natural materials — enabling it to undergo large, reversible deformations. Read the paper: Modular ...

Their device consists of 10 concentric rings of a copper-and-fiberglass metamaterial. While scientists are still far from cloaking an object in visible light, the Duke device is a first step ...

Credit: Surjadi et al, MIT The metamaterial's structure is so tiny that MIT's samples range from "several square microns to several square millimeters" across, according to the institute.

The engineers' creation is considered a "metamaterial," or a synthetic material ... to create the first large-scale invisibility cloak (à la Harry Potter) and to build a "physics-defying ...

Engineers have fabricated a metamaterial that is not only strong but also stretchy. Their new method could enable stretchable ceramics, glass, and metals, for tear-proof textiles or stretchy ...

That's a real, er, stretch. But it's exactly what a team of researchers at MIT are claiming their new "strong but stretchy" metamaterial could enable. A metamaterial, in case you're wondering ...
