我们表明，电磁波的偏振状态可以通过各向异性超材料板的反射来操纵，并且所有可能的偏振（圆形，椭圆形和线性）都可以通过调整材料参数来实现。特别地，线偏振光在一定条件下反射后将其偏振完全转换为交叉方向。微波实验成功地实现了这些想法和结果是非常符合数值模拟。
We show that the polarization states of electromagnetic waves can be manipulated through reflections by an anisotropic metamaterial plate, and all possible polarizations (circular, elliptic, and linear) are realizable via adjusting material parameters. In particular, a linearly polarized light converts its polarization completely to the cross direction after reflection under certain conditions. Microwave experiments were performed to successfully realize these ideas and results are in excellent agreement with numerical simulations.
