In a more practical vein, the finding could have profound implications for military technology, wireless communication, and even interplanetary exploration.In September, the journal accepted a paper from Smith and Schurig that proved that their method was more than just a thrilling hypothesis.

But that instant came last May with a flurry of dramatic headlines.

Wells enthusiasts, and theoretical physicists unite in a moment of ecstasy.

Leading in from the front of the apparatus is a wire that feeds microwaves toward the cylinder as it sits in the center of the bottom plate.

Around it, Smith and Schurig have arranged concentric rings of metamaterials, with the empty spaces between the rings forming narrow channels.

To similarly cloak something from electromagnetic radiation, Smith and Schurig must bend the incoming beam around the object in a tightly controlled manner.

They managed to do so using a class of recently created "metamaterials" that possess an ability, not found in nature, to bend light at extreme angles (a property known as negative index of refraction).

Although light moves through a vacuum at a constant speed, it slows down when traveling through any transparent medium, like water or glass.

Light travels faster in the hot, thin air close to the road than it does in the cold, dense air above, and that difference in speed is what causes it to shift direction as it crosses the boundary between the two.

They had succeeded in cloaking a small cylindrical object—shielding it not from visible light but from microwaves, a form of electromagnetic radiation with a substantially longer wavelength, which makes the cloaking effect considerably easier to achieve.
