How does one "unveil" an invisible man?

I read in the Sunday Times that some lab researchers are working to create ..... well here -- you read it as they state it:

Science close to unveiling invisible man
Jonathan Leake, Science Editor

INVISIBILITY devices, long the realm of science fiction and fantasy, have moved closer after scientists engineered a material that can bend visible light around objects.

The breakthrough could lead to systems for rendering anything from people to large objects, such as tanks and ships, invisible to the eye – although this is still years off.

Researchers at the University of California at Berkeley, whose work is funded by the American military, have engineered materials that can control light’s direction of travel. The world’s two leading scientific journals, Science and Nature, are expected to report the results this week.

It follows earlier work at Imperial College London that achieved similar results with microwaves. Like light, these are a form of electromagnetic radiation but their longer wave-length makes them far easier to manipulate. Achieving the same effect with visible light is a big advance.

I don't want to be a negative thinker, but I reckon that most of the magic in this report is in that phrase I highlighted! "whose work is funded by the American military"! Guess you Pilgrims din't know that the Army has their own income source -- and they aren't using your tax dollars....... NOT!
What are these tax receivers gonna report --- 'We can't see the end of the project?"
