摘要	With the rapid development of modern science, the techniques of fabricating two-dimensional surface-relief gratings with a hemispherical grid for visible light by chemical methods are proving to be successful. In this paper, we use a multi-level structure to simulate this kind of grating and adopt the Lagrange multiplier method to minimize the volume error, and the rigorous coupled-wave method is employed to analyse the vector diffraction properties of this kind of grating. By computer simulation and calculation, the relations between the reflectivity and the structure parameters of the gratings are presented, and the antireflective characteristics are also studied when visible light is incident upon them. The results show that this kind of grating is capable of reducing reflections, and could achieve very low reflectivity over a wide field of view and a wide waveband by choosing appropriate parameters. The results also show that the errors can be neglected when L greater than or equal to 16 and the results are proved to be credible.
