Physicist Andrea Alu from the University of Texas at Austin proposed an invisibility cloak that starts with the standard metamaterials - bends radiation around whoever is wearing the cloak - but adds CMOS negative impedance converters (NICs) at the corners of the cloak. In other words, it makes the current design thinner and lighter. Continue reading for videos and more information.

Obviously, the technology for this is still in its early stages and we'll need to study NICs more to understand how they work.

But this is one of the more detailed designs for an invisibility cloak that we've seen. If Alu's theory is right, we could be one step closer to creeping around in invisibility cloaks just like the famous fictional wizard himself.
