Believe it or not, researchers at the University of Texas have “for the first time, cloaked a three-dimensional object in free space; that is, no matter the angle of observation, the object was rendered invisible in 3-D.” Unfortunately, it will still be years until we see this technology on the market.

The UT team used a different method, known as plasmonic cloaking, to conceal an 18-centimeter cylinder from every direction. This is true “cloaking,” as the plasmonic material is actually coated onto the object to be concealed. These plasmonic materials work by doing the opposite of what normal materials do: reflecting light. When you see an object, it’s because light is bouncing off of it and striking your eyes, which send that info on to the brain for processing.
