If you have watched the dozens of Hollywood movies about "invisible men" over the years, you could be in for a shock.
Scientists say they are very close a process that can render people and objects invisible.
News releases this week say researchers have demonstrated for the first time they are able to cloak three-dimensional objects using artificially engineered materials that redirect light around the objects.
The process renders the objects invisible.
The research at the University of California, Berkeley, are to be released later this week in the journals Nature and Science.
The work moves scientists very close to hiding people and objects from visible light, which could have critical military use.
The report said people can see objects because they scatter the light that strikes them, reflecting some of it back to the eye.
Cloaking uses materials, known as metamaterials, to deflect radar, light or other waves around an object, like water flowing around a smooth rock in a stream.
The research was funded in part by the U.S. Army Research Office and the National Science Foundation.
