提出一种利用微波场在四能级原子系统中实现二维电磁感应光栅的理论研究方案，此原子系统中两个偶极禁戒的亚稳态之间采用微波场来耦合。分析了微波场存在与否对弱探测场夫琅禾费衍射图样的影响。讨论了有微波场存在时，探测场失谐量、控制场强度、相互作用长度等对二维电磁感应光栅衍射效率的影响。结果表明，通过合适地调节系统参数，在所研究的系统中可以实现高衍射效率的二维电磁感应光栅。该方案可应用于全光分束和光开关，对光信息处理及光网络通信研究有一定帮助。

Due to the limitations of traditional gratings, researchers began to look for new methods to fabricate gratings. In recent years, some interesting physical phenomena such as coherent population trapping, electromagnetically induced transparency, spontaneously generated coherence have attracted great attenton. If the standing wave field in the form of spatial modulation is replaced by the traveling wave field in the electromagnetically induced transparency effect, alternating high transmission regions and high absorption regions can be generated...
