That’s an improvement over early cloaking efforts where the abracadabra effect is ruined by as little as a head tilt.


And the scientists pulled it off with relatively cheap and easily found materials, specifically a set of four lenses set at just the right distance to bend light around an object.


The new research, submitted to the journal Optics Express and available on arXiv.org, is the latest in a growing body of studies exploring various approaches to making objects appear to vanish into thin air....
