If you type the word “invisible” into the search engine on arXiv.org you get a very curious result. Two papers with nearly identical titles, uploaded three days apart.
A quick scan of both papers, which are by separate groups, reveals that they are both about roughly the same thing – the first invisibility cloak that works on large objects illuminated with visible light.
This promises to be a major breakthrough in the world of cloaking and I understand that one paper is destined for a prestigious journal; I’m not sure about the other.
We have a crack reporter looking into it. More later…
In the meantime you can read the papers here and here.
