    'Cloaking' a 3-D object from all angles demonstrated

    Researchers have "cloaked" a three-dimensional object, making it invisible from all angles, for the first time. However, the demonstration works only for waves in the microwave region of the electromagnetic spectrum.

    It uses a shell of what are known as plasmonic materials; they present a "photo negative" of the object being cloaked, effectively cancelling it out.
