High optical absorption in graphene
... If we were to freely tune the optical properties of a film with the thickness of a single layer of graphene, the maximum attainable light absorption would be dictated by the contrast of the surrounding media [5]. This general limit for light absorption in ultrathin films may under favorable conditio ...

Our study is based on a set of data gathered over a large variety of particulates: latex beads (in the 0.1–2 µm range), glass beads (in the 5–20 µm range), and sands, salts, carbons, corundum, and volcanic ashes (in the 5–100 µm range). Latex beads are likely to be perfectly spherical, and are suppo ...

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.
