Source: Nature Photonic Metasurfaces – Exploring the World of Flat Optics Understanding Photonic Metasurfaces Introduction to Metasurfaces Photonic metasurfaces are surfaces with nano-scale structures that exhibit unique optical properties. These structures are often thinner than the wavelength of light. While similar to photonic metamaterials, metasurfaces differ in that the sub-wavelength structuring is applied only on […]
