Research team proposes a novel type of acoustic crystal with smooth, continuous changes in elastic properties

In dim light a cat sees much better than you do, as do dogs and nocturnal animals. That's because the structure of a cat's eye has a tapetum lucidum, a mirror-like layer immediately behind the retina. Light entering the eye ...
