摘要： The present disclosure describes anti-reflective structuring of optical elements that include a metasurface. In some implementations, the anti-reflective structuring includes applying one or more anti-reflective coatings over a surface of the metasurface. In some implementations, the anti-reflective structuring includes modifying the shape of the meta-atoms or providing textured features on the meta-atoms so as to reduce reflections.
