Invention of stealth material

Recent research by British scientists has invented a new method for creating invisibility materials when interacting with sunlight.

These artificial "metamaterials" can "bend" light in some way to make objects invisible.

But a team of researchers from the University of Cambridge has discovered a special technique to create "metamaterials" that, when interacting with light in a particular way, will cause objects to "disappear" or look like something else.

Researchers used unfocused laser light to string together gold nanoparticles in water. These nanoparticles stacked on top of each other like LEGO bricks. This allowed the researchers to produce even more of the material.

Next, scientists use barrel-shaped molecules called cucurbiturils as spacers between the nanoparticles to hold them in place. At the same time, they must control the welding process to prevent melting and allow electricity to pass through them.

The research team also used laser light to create ripples of electrons on the surface of the material, called plasmons. After the charged particles absorb light, the atoms on the surface fill the nanoparticles, causing the object to disappear.

These "metamaterials" could be used for everything from drugs and explosives to military stealth applications.

First, the "metamaterial" will be successfully tested on a small scale before being applied to a larger scale.
