我们的实验表明，由两个相干的反向传播光波形成的驻波可以采取各种形式，提供了新的方法来询问和控制的偏振敏感的光-物质相互作用在λ（亚波长厚度）介质。与常见的能量驻波相反，极化驻波具有恒定的电能密度和磁能密度以及沿波轴沿着周期性变化的极化状态。与直觉相反的是，通过调节各向异性的偏振（Meta）材料的方位角，可以使其对这种偏振变化敏感或不敏感。
We experimentally demonstrate that standing waves formed by two coherent counter-propagating light waves can take a variety of forms, offering new approaches to the interrogation and control of polarization-sensitive light-matter interactions in ultrathin (subwavelength thickness) media. In contrast to familiar energy standing waves, polarization standing waves have constant electric and magnetic energy densities and a periodically varying polarization state along the wave axis. counterintuitively, anisotropic ultrathin (meta)materials can be made sensitive or insensitive to such polarization variations by adjusting their azimuthal angle.
