This "cloak" only works on microwaves and in two ... one based in London — develop a more effective metamaterial from calcite crystals, which are much cheaper than, well, gold-etched silk.

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 ...

A new software that simulates complex wave scattering for metamaterial design could bring the invisibility cloak a step closer to reality. Developed by researchers at Macquarie University ...

For example, a metamaterial invisibility cloak would bend the paths of light waves around a cloaked object, accelerating them on their way, and reunite them on the other side. Thus, an onlooker could ...

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 ...

enabling transformative technologies such as superlenses and cloaking devices. Now, carefully arranged arrays of atoms have brought these possibilities a step closer, achieving negative refraction ...

Robust growth is spurred by advancements in telecom, healthcare, and aerospace & defense sectors. The drive for 5G infrastructure, metamaterials in a ...
