Physicist Andrea Alu of the University of Texas has presented an 'invisibility cloak' which, in addition to the (already tested) use of metamaterials, adds a CMOS 'inverter' to the corners of the device, making it thinner and lighter.
The effect is impressive and tangible: makes us understand how this 'camouflage' mechanism will soon be used, probably in the military field, even if it would have an enormous series of possible applications (even in ethology: the study of animal species would be facilitated by the possibility of being in physical presence without disturbing the observed subjects).
Here are a couple of videos to focus on what we are talking about:
