[0002] A circulator is a multi-port device with unidirectional transmission characteristics. Its main function is to make the signal flow through adjacent ports in a specific direction while achieving high isolation and blocking of reflected signals. It can transmit the incident wave entering any port to the next port in the direction determined by the static bias magnetic field. This characteristic makes the circulator play an important role in applications such as isolators, duplexers, and reflection amplifiers.
