How SUGAR could make stealth jets invisible: Anti-reflective coating made from sucrose conceals aircraft from radar

Flying under the radar has long been the aim for pilots on secret missions. Now scientists have developed a lightweight anti-reflective coating based on the structure of a moth's eye that could make aircraft invisible to radar. The secret to the new coating is the creation of millions of tiny hollow spheres of carbonised sugar, arranged in a tightly-packed hexagonal monolayer.
