Invisibility

Scientists are investigating using variations of density in ocean water to cloak oil rigs from dangerous surface waves.

Scientists have created an array of microlenses that slow down or stop light, which could be used to identify biological substances.

Mathematicians are proposing a cloaking system, which could allow buildings to be rendered "invisible" to earthquakes.

Researchers have cloaked a three-dimensional object standing in free space with the use of plasmonic metamaterials.

Scientists have created a device that guides sound waves around a central area, essentially acting as an "invisibility cloak for sound."

Scientists have discovered that objects coated with a forest of carbon nanotubes can be made to disappear against a dark background.

A new "invisibility cloak" utilizes the same effect that causes mirages to appear.

BAE has developed and "invisibility cloak" technology called "Adaptiv" that renders vehicles invisible in the infrared part of the spectrum and can even let the vehicle mimic other vehicles or natural objects.

Duke University scientists have outlined a theory for the use of metamaterials in facilitating more efficient wireless power transfer.

Researchers are reporting the development of a new "carpet cloak" technology that is only a few times larger than the objects it conceals.

Using naturally occurring crystals rather than metamaterials, two research teams working independently have demonstrated technology that can cloak larger objects in the broad range of wavelengths visible to the human eye.

Scientists have determined that it should be possible to create a spacetime cloak, that hides entire events.
