Metamaterials are rapidly developed novel artifical materials whose permittivity and permeability are arbitrary and then they can control the electromagnetic wave propagation. The basic electromagnetic theory of invisibility cloak based on coordinate transformation is introduced, and the research progress in metamaterials electromagnetic invisibility cloak is reviewed. Closed invisibility cloak, external invisibility cloak and invisibility carpet are discussed in detail. These cloaks show very good invisibility performance and have very important applications, especially in the military.%超介质(Metamaterials)是近年迅速发展起来的能够获得任意介电常数和磁导率进而调控电磁波传播的新颖介质.介绍了基于坐标变换的电磁隐身斗篷的基本理论,综述了超介质电磁隐身斗篷的研究进展,包括“封闭式”隐身斗篷、外隐身斗篷、隐身地毯等几种不同的隐身斗篷,这些隐身斗篷都具有良好的隐身效果,在隐身技术方面,尤其是在军事方面具有非常重要的应用价值.
