Playing with light and symmetry
December 05, 2024
In a recent study at the University of Twente, researchers discovered a way to scatter light in a special, symmetrical way using nanotechnology. This has potential for future technologies such as anti-counterfeiting
For the study, the researchers printed cubes about five times smaller than the diameter of a human hair, which consisted of rods in random directions. But by deliberately applying mirror symmetry to the cubes, something surprising happened. There was a huge increase or decrease in light intensity right on the symmetry line.
