Isotropic beacon

An isotropic beacon is a hypothetical type of transmission beacon that emits a uniform EM signal in all directions for the purposes of communication with extraterrestrial intelligence.^[1]

Isotropic beacons and their relation to SETI[]

An isotropic beacon can be any transmitter that emits a uniform electromagnetic field. However, the term is most commonly used to describe a transmitter used by a civilization to call attention to itself over interstellar distances.^{[citation needed]} Project Cyclops is and was one of the first looks at the theoretical framework of what it would take to create such a device.^{[citation needed]}
