艾里光束（Airy beam）是近年来备受关注的新型无衍射激光束之一，艾里激光束具有自由加速、无衍射及自愈等奇异特性，并具有重要应用前景。超常介质为人工微结构材料，它使人们具备按需要设计介质参数的能力。基于一维光束传输方程，获得了超常介质中艾里光束复振幅传输解析表达式。数值计算结果表明，超常介质中艾里光束振幅的大小与在正常介质中完全相同，而振幅的虚部和相位正好相反。所得结果为人们操控艾里光束提供支持。

The Airy beam is a new kind of non-diffracting beam discovered in recent years. Airy beams have exotic characteristics such as free acceleration, non diffracting laser beam and self-healing, and so have important application potentials. Metamaterials are artificial microstructures material, which permit people to design electromagnetic parameters of media at will. Based on the paraxial wave equation, the analytical expression of complex amplitude of Airy beams in meta-materials is obtained; in addition, the numerical results show that, the module of complex amplitude of Airy beams in meta-materials is similar to that of conventional medium, while the imaginary part and the phase complex amplitude are opposite. The results may provide support for people to better manipulation of the Airy beam.
