A New Science post reports that the camouflage will likely be comprised of microscopic engineered structures that bend light around the object, in this case, a soldier. One Karlsruhe Institute of Technology professor, Martin Wegener, and his team have created cloaks made from photonic crystals which work for certain wavelengths. But, as bending light over the entire spectrum would violate Einstein's theory of relativity, Wegener said the technology would make the soldier appear more like a ghost or colored shadow than completely invisible.
Another professor, John Pendry of the Imperial College London who has pioneered metamaterials, wrote in a New Scientist article, "The Invisible Soldier," that metamaterials expand beyond chemical composition by using artificial structures that might only be nanometers in diameter for visible light.
Pretty cool, no? Here's what it might look like:
Even better, no?
Well, maybe not. New Science apparently didn't know about or read the HSB webpage. Evidently, federal regulators are involved.
HSB reported on May 18, 2015, that the Army canceled HSB's RFP for light weight, passive (non-powered) adaptive camouflage. Why? HSB couldn't submit its material under the Small Business Innovation Research (SBIR) rules. Why? Any firm submitting the proof of concept under SBIR rules must be US-based and the majority of owners must be U.S. citizens.
Go and figure.
Let the discussion begin...
