摘　　要：采用线性传输矩阵法研究了Faraday位型下含石墨烯层的反铁磁光子晶体的Faraday效应.当电磁波垂直入射到石墨烯反铁磁体系时,给出这种位型下的色散关系,设定不同介质中电磁波磁场的波解形式,通过电磁场的边界条件得出传递矩阵,最后给出不同种一维石墨烯反铁磁光子晶体的透射率和Faraday旋转角的表达式并进行数值模拟.研究了两种结构下的石墨烯磁性光子晶体的透射率及法拉第旋转随层数的变化关系,电介质排布有所不同,会导致其透射率发生很大变化.当只在光子晶体中间的反铁磁层上覆盖单层石墨烯薄膜时,发现在THz频域范围内,光子晶体会增强石墨烯对泵浦波的吸收.The Faraday effect of graphene and magnetic photonic crystal structure are studied by means of linear transfer matrix method in Faraday mode. When the electromagnetic wave is incident to the graphene antiferromagnetic system, the dispersion relation of this type is given. The wave form of electromagnetic field in different medium is set, and the transfer matrix is obtained by the boundary condition of the electromagnetic field. At last, the expression of the transmission and Faraday rotation angle of the different kinds of one -dimensional graphene anti ferromagnetic photonic crystal are given. The transmittance of graphene magnetic photonic crystals and faraday rotation changes with the number of layers are studied. Different dielectric arrangement will lead to great changes of the transmittance.
