In optics and telecommunication, the term corner reflector has the following meanings:
1. A retroreflector consisting of three mutually perpendicular, intersecting flat surfaces, which returns a reflected electromagnetic wave to its corner reflector point of origin. The three corner reflector antenna intersecting surfaces often have square corner reflector wireless antenna shapes. This is also known as a corner cube.
One such device, radar corner reflector beamwidth normally consisting of three conducting radar corner reflector metallic surfaces or screens perpendicular to one another, is designed to act as a radar target or marker and are often employed on ships and, especially, lifeboats. Another such device uses passive optical mirrors which returns an incident light beam in the opposite direction. Arrays of such retroreflectors hawking tech 15 dbi corner reflector antenna are used in bicycle reflectors, automobile tail lights and as corner cube reflector targets for laser range finding. Microscopic corner reflector structures can be incorporated into reflective corner reflector construction paint for increased visibility at night (although retroreflective spherical beads (see retroreflector reflector corner cube article) are more common for this purpose).
Tower blocks with balconies are often accidental corner reflectors for sound and return a distinctive echo to an observer making a sharp noise, such as a hand clap, nearby.
2. A directional antenna using two mutually intersecting conducting flat surfaces.
3. corner reflector uhf antenna In radar interpretation, an object that, by means of multiple reflections from smooth surfaces, produces a radar return of greater magnitude than might be expected from the physical size of the object.

Electronics Topics
The field of electronics is the study and use of systems that operate by controlling the flow of electrons or other electrically charged particles in devices such as thermionic valves and semiconductors. The design and construction of electronic circuits to solve practical problems is part of the fields of electronic engineering, and the hardware design side of computer engineering. The study of new semiconductor devices and their technology is sometimes considered as a branch of physics.
