▎ 摘　　要

NOVELTY - The method involves obtaining working efficiency curves at different frequencies in a target application scene. A Fano resonance frequency range of a graphene symmetrical structure magnetic sensor is determined according to the working efficiency curve. A response spectrum of the graphene symmetrical structure magnetic sensor is obtained. A physical parameter of the graphene symmetrical structure magnetic sensor is adjusted until the adjusted response spectrum of the graphene symmetrical structure magnetic sensor accords with the narrow line width and the high spectrum contrast according to a difference of a line width reflected by the response spectrum and a preset narrow line width and the difference of the spectrum contrast reflected by the response spectrum and the preset high spectrum contrast. USE - Graphene symmetrical structure integrated magnetic sensor parameter determining method. Uses include but are not limited to power electronic technology, energy management, computer technology and automobile industry. ADVANTAGE - The graphene symmetrical structure magnetic sensor prepared based on the physical parameter obtained by the method can improve the sensitivity of the sensor structure to the magnetic field change, so as to improve magnetic field measuring sensitivity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a graphene symmetrical structure preparation method; (2) a magnetic field measuring method applied to the graphene sensor with non-symmetrical structure; (3) a parameter determining device of a magnetic sensor with a graphene symmetrical structure. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating a graphene symmetrical structure integrated magnetic sensor parameter determining method.
