摘　　要：近年来人工电磁材料器件已经成为在亚波长尺度上调控电磁波的重要工具,因为它很容易根据电磁谐振器周期单元结构阵列来设计其光学特性,如折射率、介电常数和磁导率等等。人工电磁材料具有很多奇异性质,这也使其具有可调控、传感和吸波等特性。In recent years, metamaterials devices have become an important tool to regulate electromagnetic waves on a subwavelength scale, because it is easy to design their optical properties, such as refractive index, dielectric constant and permeability, according to the periodic cell structure array of electromagnetic resonators. Artificial electromagnetic materials have many strange properties, which also make them have controllable, sensing and absorbing properties.
