Learning how to accurately control the optical response of these nanoantennas represents a very promising approach to the control of the distribution of light fields over space and time on the nanometer scale. Traditionally, two main complementary approaches have been followed in order to control th ...
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.
