我们提出了一种在不同入射波偏振下具有多种功能的各向异性均质超材料平板。通过基于麦克斯韦方程的理论分析，我们证明了具有定制本构参数的单个一维各向异性超材料板在不同偏振波的照射下可充当带通滤波器、透明壁和偏振转换器。我们提出了一种特殊的结构单元来实现各向异性超材料的定制本构参数张量，并由此设计和制造了三维超材料平板。测量结果与理论计算和全波模拟非常吻合，证明了单块超材料板的偏振控制多种功能的优异性能。
We propose an anisotropic homogeneous metamaterial flat plate having multiple functionalities under different polarizations of incident waves. From the theoretical analysis based on Maxwell's equations, we demonstrate that a single one-dimensional anisotropic metamaterial slab with the tailored constitutive parameters serves as a bandpass filter, a transparent wall, and a polarization converter under illuminations of differently polarized waves. We present a special structural unit to realize the tailored constitutive parameter tensors of the anisotropic metamaterial from which a three-dimensional metamaterial flat plate is designed and fabricated. The measured results agree very well to theoretical calculations and full-wave simulations, demonstrating the excellent performance of the polarization-controlled multiple functionalities of the single metamaterial plate.
