The optical properties of a material are predominantly determined by its constituent atoms and electrons and the way that these respond to electromagnetic waves. In natural materials, the diversity of possible optical characteristics is limited, and so metamaterials—artificial structures engineered to control the propagation of light—offer hope for a plethora of novel optical applications.
