Physicists at New York University have discovered a novel class of engineered materials called gyromorphs that can completely block light from propagating in any direction. Unlike conventional photonic crystals that require rigid periodic grids—and often allow light to leak through at specific angles—gyromorphs combine random spatial clustering with a subtle ring-like distance order. Reported by Science News, this breakthrough overcomes a long-standing barrier in optics and could enable ultra-efficient optical computer chips, lossless waveguides, and next-generation light sensors.
