We've heard of these kinds of guys before. They've spent too much time engrossed in Harry Potter books or old Star Trek episodes, and dream of some sort of device that will make them invisible. Every couple of years, one of them surfaces with a new idea about a "cloaking device" that can bend light around solid objects, making them appear to be invisible. This time, two separate teams in the UK are racing to show that the concept is feasible. One group, at Imperial College in London, believes that light-bending metamaterials can be produced within the next decade. Meanwhile, two mathematicians have published a study in the Proceedings of the Royal Society, which claims that a "superlens" placed close to an object could produce an "anomalous localized resonance," essentially rendering the underlying object invisible by creating a phantom light wave using the same frequency. The scientists envision building a device soon -- one that could conceivably cloak particles of dust. We'll check back with both parties in a few years. In the meantime, we'd like to present our detailed artist's rendering, prepared at great cost and with much research, which we believe truly shows what a cloaked object will look like to the naked eye.
