Visible Light, Wide-Angle Graded Metasurface for Back Reflection
... stemming directly from reciprocity,28,29 and it is not limited to our particular configuration. More specifically, if the surface is designed to back reflect with x% efficiency for the AOI θi, it ensures (100 − x)% coupling to the specular direction (θr = θi). Reciprocity then ensures that, when the dire ...

Retroreflector
A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects light back to its source with a minimum of scattering. In a retroreflector an electromagnetic wavefront is reflected back along a vector that is parallel to but opposite in direction from the wave's source. The angle of incidence at which the device or surface reflects light in this way is greater than zero, unlike a planar mirror, which does this only if the mirror is exactly perpendicular to the wave front, having a zero angle of incidence.
