我们提出了一种简单的磁光远场弗劳恩霍夫衍射理论。该理论已发展为正常入射，在大晶格间距和可忽略的边缘效应的限制。推导出了解析表达式，并作出了一些实验学家应该感兴趣的预测。例如：(i)在极角θ的衍射阶上，s和p入射偏振的复克尔旋转之比等于cos2（θ）。（ii）磁点所占的相对面积在镜面反射时可引起克尔旋转的共振。
We present a simple theory of magneto-optical far field Fraunhofer diffraction by a regular array of magnetic dots. The theory has been developed for normal incidence, in the limit of large lattice spacings and negligible edge effects. Analytical expressions were derived, and several predictions made, that should be of interest to experimentalists. For instance: (i) in the diffraction order of polar angle θ, the ratio of the complex Kerr rotations for s and p incident polarizations is equal to cos2(θ). (ii) the relative area occupied by the magnetic dots can induce a resonance of the Kerr rotation at specular reflection.
