ANSI and IEC standard schematic symbol for a circulator (with each waveguide or transmission line port drawn as a single line, rather than as a pair of conductors). In electrical engineering, a circulator is a passive, non-reciprocal three- or four-port device that only allows a microwave or radio-frequency (RF) signal to exit through the port directly after the one it entered.
Optical Circulator symbol. An optical circulator is a three- or four-port optical device designed such that light entering any port exits from the next. This means that if light enters port 1 it is emitted from port 2, but if some of the emitted light is reflected back to the circulator, it does not come out of port 1 but instead exits from port 3.
Symbol for a 3-Port Circulator. In electrical engineering, an active circulator is an active non-reciprocal three-port device that couples a microwave or radio-frequency signal only to an adjacent port in the direction of circulation. Other (external) circuitry connects to the circulator ports via transmission lines.
In acoustical engineering, an acoustic circulator is a non-reciprocal three-port device that couples airborne sound waves only to an adjacent port in the direction of circulation. Compared to radio frequency (RF) and microwave circulators, acoustic circulators are for airborne sound waves rather than for RF and microwave electromagnetic signals.

Port 1 is the input port where power is applied. Port 3 is the coupled port where a portion of the power applied to port 1 appears. Port 2 is the transmitted port where the power from port 1 is outputted, less the portion that went to port 3. Directional couplers are frequently symmetrical so there also exists port 4, the isolated port.
Ohio State was No. 1 in the final Associated Press Top 25 college football poll of the season Tuesday after beating Notre Dame for its first national championship since 2014. The Buckeyes (14-2 ...
