论文摘要
自我平衡的元流域由于其独特的频率独立传播和反射特性以及平面波的极化变换的可能性而引起了极大的关注。在本文中，我们专注于近场频谱，以在理论和实验上研究由各向异性自我平衡跨面支持的表面波的特性。我们表明，由于电磁Babinet的二元性，这种结构对于任何频率都是双曲线的。我们通过证明沿两个主要方向的表面波的宽带TE-TM极化退化来揭示了平面波固有的极化程度。我们证明了通过非常小的频移切换90度的载管方向的可能性，从而为极端的可调性和表面波路由铺平了道路。结果获得了很多实用应用的机会，包括平坦的极化设备，光学数据处理系统和天线。
Self-complementary metasurfaces have gained significant attention due to their unique frequency-independent transmission and reflection properties and the possibility of the polarization transformation of plane waves. In this paper, we focus on the near-field spectrum to investigate both theoretically and experimentally the properties of surface waves supported by anisotropic self-complementary metasurfaces. We show that as a consequence of the electromagnetic Babinet's duality, such structure is hyperbolic for any frequency. We reveal the polarization degree of freedom inherent to plane waves by demonstrating the broadband TE-TM polarization degeneracy of the surface waves along two principal directions. We demonstrate the possibility of switching the canalization direction of 90 degrees by a very small frequency shift paving a way to the extreme tunability and surface wave routing. The results obtained open a plethora of opportunities for practical applications, including flat polarization devices, optical data processing systems and antennas.
