摘　　要：在穿孔金属/反铁磁(PMA)结构,利用线性传递矩阵方法研究结构Voigt位型下光透射非倒易性.发现外加静磁场和穿孔金属孔几何尺寸对结构的透射光谱产生影响,出现了光透射非倒易性现象.光透射非倒易性频率区域在反铁磁共振区,此区间正处于太赫兹(THz)波段,随着入射角度的增加,透射非倒易性的效果越明显,研究穿孔金属/反铁磁结构的光透射非倒易性可为反铁磁器件的设计加工提供理论基础.The nonreciprocal of light transmission with perforated metal / antiferromagnetic（ AF）structure（ PMA） in Voigt geometry is calculated. The calculations are performed with a linear transfer matrix method and examples of nonreciprocal of light transmission are given. In particular,the nonreciprocal of light transmission in PMA is studied when the direction of an applied magnetic field and Perforated metal hole geometry size. The nonreciprocal of light transmission can be relized in a resonance zone of AF,including terahertz（ THz） frequency range. The increasing of the angle of incidence wave can enhance the effect of nonreciprocal of light transmission,AF may be of interest in signal processing in the THz.
