Tensor Holographic Metasurface for Independently Manipulating Multibeams

Based on the principle of surface impedance superposition, a tensor holographic metasurface capable of independently controlling the refraction angles and polarization of dual beams is proposed. The underlying principle is the impedance superposition of multiple tensor holographic metasurfaces with different impedance distributions. To validate this method, a multiplexed metasurface shared by two beams is proposed. The simulation results show that the deflection angles and polarization states of the two beams can be flexibly manipulated. This metasurface with low profile, light weight and compact aperture is expected to be used for wireless communications.
