▎ 摘　　要

NOVELTY - The rotator has a main body provided with a single layer graphene sheet (2a) that is connected with a circular waveguide (1). The circular waveguide is formed with an inner microwave frequency section. A multi-layer graphene sheet (2) is connected with a solenoid module (3) by a first solenoid (3a) and a second solenoid (3b). The solenoid module is connected with a microwave signal transmission direction inner circular waveguide. The multi-layer graphene sheet and an inner part of the module are connected with the single layer graphene sheet in a parallel manner according to certain pitch. USE - Graphene magnetic adjusting faraday rotator. ADVANTAGE - The rotator is simple and compact in structure, simple to control and easy to integrate and use, and has less volume, and realizes graphene magnetic adjusting faraday rotating process at certain range in an accurate manner. The solenoid module can control size of electric current to bias fixed intensity of external magnetic field in an electromagnetic wave circular waveguide TE11-mode, so that bias magnetic field is generated in a low electromagnetic wave transmission unit through a graphite mold for determining a deflection angle in an effective manner.
