我们证明了二维完全光子带隙（PBG）可以在包含各向异性左手超材料层的双层单元胞的层状周期结构中实现。在此基础上推导了实现二维完全PBG的几何参数和材料参数准则，并给出了详细的相图。我们讨论了该机制的基本物理原理，并用几个具体的例子说明了完整的带隙效应。
We demonstrate that a two-dimensional complete photonic band-gap (PBG) can be realized in a layered periodic structure with a double-layer unit cell containing an anisotropic left-handed metamaterial layer. A set of criteria is derived for the geometric and material parameters to realize a two-dimensional complete PBG in such systems, and a detailed phase diagram is given. We discuss the underlying physics of the mechanism and illustrate the complete band-gap effects with several concrete examples.
