Abstract
Electrically thin and effectively two-dimensional material composites, metasurfaces, have been widely exploited for manipulation of electromagnetic waves. For many applications it is desired to transform incident waves of a specific frequency range keeping the metasurface invisible at other frequencies. Such frequency-selective response can be achieved based on subwavelength Huygens’ inclusions. However, their fabrication requires sophisticated processes due to the three-dimensional geometry. Here, we propose a planar Huygens’ meta-atom with the goal to open a way to realize broadband invisible metasurfaces with topologies suitable for the conventional printed circuit board fabrication technology. We synthesize and analyse, both numerically and experimentally, three different metasurfaces capable of polarization and amplitude transformations of incident waves.
