A corner reflector is a retroreflector consisting of three mutually perpendicular, intersecting flat surfaces, which reflects waves back directly towards the source, but shifted (translated). The three intersecting surfaces often have square shapes. Radar corner reflectors made of metal are used to reflect radio waves from radar sets. Optical corner reflectors, called corner cubes, made of three-sided glass prisms, are used in surveying and laser rangefinding.
The term is also used for a corner reflector antenna, consisting of two flat metal surfaces at a right angle, with a dipole antenna in front of them.

“Many said selfishness was the flaw of our modern age; but then self-conceit emerged from a corner of the deepest hell to join selfishness.”
