Cloak of invisibility to aid semi business

Scientists who have developed a so-called “cloak of invisibility” are confident that the material will have applications in the semiconductor industry.

According to the BBC, a research team at the University of California, Berkeley, believe the material, based on dielectrics, will overcome the obstacles encountered by previous scientists who have made cloaks of invisibility using metal materials.

Xiang Zhang, professor of mechanical engineering at Berkeley, explained that the silicon based material bends around the “cloak”. Zhang changed the optical density of the material by drilling holes smaller than the wavelength of light.

The demonstration doesn’t mean that you can behave like the invisible man, because the so-called cloak is only a few thousandths of a millimetre. But at that size he believes there’s still applications.

He told the BBC that the discovery could save the semiconductor industry millions of dollars by using the cloak to hide flawed parts of the masks used to create chips.
