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 ...
Exploring wave propagation and localization in various media has been a core focus in optics and acoustics. Specifically, in photonics and phononics, scientists have been dedicated to understanding and controlling the behavior ...
