Metamaterials feature negative refractive index ...

a person submerged in a swimming pool filled with a hypothetical liquid with negative N would appear to float above the pool instead of appearing to be beneath the surface.

Just great. If my girlfriend gets ahold of some of that stuff I'll never find the remote.

Very interesting Thomas ...


The tech behind it makes total sense.

Cloaking something cylindrical seems to be the first thing that'll get accomplished, ... but I'd say that difficulty will arise when complex shapes and curvy structures are attempted. Bending light around something continuos like a cylinder is one thing, ..but when the light has to take more than one turn with something say like a head shape, ... that might prove difficult to not produce a visual warping effect -- sort of like in the movie Predator.

Fascinating all the same.

The other issue is that ... the person covered with such material will be in complete darkness. All light is efficiently redirected around you and inside you are in pitch black. So, there will have to be some holes for the eyes ...
