Independent controls of orthogonally polarized transmitted waves using a Huygens metasurface

An ultrathin Huygens metasurface is proposed to manipulate orthogonally polarized transmitted waves independently. The Huygens metasurface consists of two layers of dielectric substrates and three layers of artificial metallic structures with ultrathin electric thickness. In physics, two orthogonal electric dipoles and two orthogonal magnetic dipoles are supported by each unit cell of the metasurface, which enable the complete control of phase distributions in both vertical and horizontal directions. Based on this feature, a polarization beam splitter with large splitting angle is designed and fabricated to demonstrate the capability and flexibility of the proposed Huygens metasurface. The numerical simulations and measurement results have a good match, indicating the good performance on independent controls of orthogonally polarized transmitted waves. An ultrathin Huygens metasurface is proposed to manipulate orthogonally polarized electromagnetic waves independently in the transmission mode. Two orthogonally electric dipoles and two orthogonally magnetic dipoles are supported by the proposed unit cells, which enable the complete controls of phase distributions in both vertical and horizontal directions. A polarization beam splitter is then designed and fabricated using the proposed metasurface. Both simulation and measurement results show good performance on the independent manipulations of orthogonally polarized waves.
