This letter demonstrates that glide symmetry can be used to match the impedance of highly dense dielectric profiles in wide angle and broad bandwidth. Using glide-symmetric metasurfaces permits tuning the magnetic properties of materials, so high values of permittivity can be matched to free space in wideband. This matching is achieved without disturbing the performance of the device, since the refractive index remains fixed. The performance of the proposed matching method is validated through measurements for normal incidence. For oblique incidence, a hyperbolic dielectric lens is matched with glide-symmetric structures in simulations. These simulations demonstrate a smooth transmission of the fields, manifesting a well-matched profile of the lens.

使用滑动对称超表面的广角阻抗匹配

这封信表明滑动对称性可用于匹配广角和宽带宽中高密度电介质剖面的阻抗。使用滑动对称超表面可以调整材料的磁性，因此可以将高介电常数值与宽带中的自由空间相匹配。这种匹配是在不干扰器件性能的情况下实现的，因为折射率保持固定。所提出的匹配方法的性能通过对正入射的测量得到验证。对于斜入射，双曲介质透镜与模拟中的滑动对称结构相匹配。这些模拟证明了场的平滑传输，表现出匹配良好的透镜轮廓。
