Ever wondered what's at the end of the rainbow? Well, Towson University scientists may be the first people who could tell us if there's a pot of gold using their rainbow trap.
Here's an excerpt:
"Those Care Bears can step off, because now humans have control over rainbows too. Scientists have created a rainbow trap with a lens and a plate of glass, and could apply the technique to information storage in the not-so-distant future.
New Scientist notes that UK scientists at the University of Surrey proposed a rainbow trap in 2007, based on exotic metamaterials that could manipulate light. But a team at Towson University in Baltimore, Maryland has managed the feat with a relatively simple setup.
One side of the lens received a 30-nanometer-thick coating of gold film, or about three times the thickness of a bacteria's cell wall. Researchers laid that gold-side of the lens down on a similarly gold-coated glass slide, so that just a thin layer of air existed between the curved lens and flat slide."
