Tiny "invisibility cloak" is like a magic carpet

Researchers have created a "carpet cloak" that
conceals objects under it from detection using light
near the human-visible part of the spectrum.

Re­search­ers have cre­at­ed a ti­ny “car­pet cloak” that con­ceals ob­jects un­der it from de­tec­tion us­ing light near the hu­man-vis­i­ble part of the spec­trum. While the car­pet it­self is vis­i­ble, the bulge of the ob­ject un­derneath it “dis­ap­pears” from the view of in­stru­ments that use this near-infrared light.

Re­search­ers say they’re hope­ful that with more pre­cise fab­rica­t­ion their strat­e­gy should yield a true “in­vis­i­bil­ity car­pet” that works in the ar­ea of the col­or spec­trum uti­lized by hu­man eyes, and at a larg­er size.

The car­pet works such that shin­ing a beam of light on the bulge shows a re­flec­tion iden­ti­cal to that of a beam re­flected from a flat sur­face.
