Background

A circulator (also called a circulator) is a multi-port device that transmits an incident wave entering any one of its ports to the next port in the order of the direction determined by an electrostatic bias magnetic field. It controls the transmission of electromagnetic wave along a certain circular direction, but the reverse direction is not. The circulator has a branch transmission system with non-reciprocal characteristic, and a commonly used ferrite circulator is a Y-shaped junction circulator which is composed of three branch lines which are symmetrically distributed at an angle of 120 degrees with each other. The principle of the unidirectional transmission is that a ferrite gyromagnetic material is adopted. Under the combined action of an external high-frequency wave field and a constant direct-current magnetic field, the material generates gyromagnetic characteristic (also called tensor permeability characteristic), namely the gyromagnetic characteristic, so that the electromagnetic wave propagating in the ferrite generates polarization rotation (Faraday effect) and strong absorption of electromagnetic wave energy (ferromagnetic resonance), and a junction isolator and a circulator are manufactured by utilizing the gyromagnetic phenomenon.
