Man, that headline doesn't really sell the sarcasm. FTA: Smith says that cloaking technology could remove cell-phone interference in buildings, letting people have clear conversations even inside an elevator.
The article's amazing headlin, "Invisibility Cloak Closer Than Ever to Reality," is some what deceptive, FTA: The Duke cloak does have its limitations. It only works in two dimensions. Both the background and the hidden object must also both be wrapped in the metamaterial.
So... how is that invisible exactly? Isn't it just blending in at that point?
