超构材料通常由亚波长的周期性谐振单元组成，具有自然材料所不具备的超常电磁特性，为操控电磁波提供了全新的技术途径。色散是材料的固有属性，调节亚波长结构的电磁共振可以实现奇异的色散特性，从而突破传统定律限制，实现对电磁波的任意操控，由此产生了一系列全新的应用，如超分辨成像/光刻、高效电磁吸收/辐射、平面光子器件等。本文总结了超构材料中色散调控的基本理论和几种典型方法，介绍了其在相关领域的应用，并对超构材料的发展前景作出展望。

Metamaterials (MMs) composed of periodic resonant subwavelength structures exhibit exotic electromagnetic properties that do not exist in nature, and open an avenue for electromagnetic waves (EMWs) manipulation. Dispersion is an inherent property of MMs. By engineering the electromagnetic resonances of MMs, extraordinary dispersion can be achieved thereby one can break the traditional physical laws and manipulate the EWMs at will. Subsequently, a serial of applications emerge including super-resolution imaging/lithography, electromagnetic absorber/radiator and planar optical devices. In this review, we summarize several typical approaches, theories and relevant applications of dispersion engineering of MMs.
