Cloaking Device Revealed. in a joint effort, US and British scientists succesfully make a copper cylinder invisble to microwaves at Duke University thanks to metamaterials. (Previous invisibility posts on the Blue.)

Science imitates Star Trek, again. Physicists Nicolae Nicorovici and Graeme Milton have published a paper in the Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences outlining a theoretical means for constructing a cloaking device. A superlens constructed from a metamaterial with a negative refractive index could be used to create a resonance that cancelled the light coming off of a (very small) object, rendering it invisible.
