Transparency and matte appearance are both vital properties of optical materials, but conflicting with each other. This research direction is about the manipulation of these optical properties using macroscopic optical metasurfaces. By exploiting extremely asymmetric diffusion of light enabled by disordered metasurfaces, we have recently developed an approach to solve this long-standing conundrum. Our design utilizes the reciprocity principle and space inversion to guarantee broadband transparency despite the randomness in the metasurface (Read more). We further leveraged the asymmetric backgrounds to widen the optimal diffusion efficiency to the full visible spectrum and realized macroscopic samples for white light. Such a principle can enable transparent display and augmented reality with preserved high clarity, and endow matte materials like walls and paper with perfect transparency.
