Sentences with phrase «invisibility device»

An invisibility device should guide light around an object as if nothing were there, regardless of where the light comes from.

But a team of theorists believe that such a set - up could make the first soft, tunable metamaterial — a vital part of an invisibility device.

Leonhardt is best known for his work on how metamaterials can be used to fashion invisibility devices and how fiber optics can be used to produce analogs of the event horizon, the point of no return in black holes.

Ideal invisibility devices are impossible, owing to the wave nature of light.

Although invisibility devices were invented first, the illusion technology might win the race to be put to practical use.

Not exact matches

His device could block thermal signatures (leading to invisibility) and provide illusionary camouflage at the same time.

Researchers crossing Albert Einstein's theory of relativity with the theory of invisibility cloaks have discovered such devices won't work at high speeds

The breakthrough in this work: Smith's metamaterial device is the first to handle a very wide range of wavelengths, a necessity for Harry Potter — level invisibility.

For example, building a useful invisibility cloak — the kind that could hide a person or a military tank — requires crafting many little devices that pick up a ray of light on the far side of an object, away from the observer, and then relay that ray, row by row, around the object.
