Novel Huygens Metasurface with Capability of Anomalous Transmission

A novel Huygens particle, of which transmission magnitudes and phases can be controlled independently,is proposed here. The transmission magnitude can be arbitrarily tuned from 0 to 0.9,while the transmission phase is between 0 and 2 pi. Aligning Huygens particles based on generalized snell's law,a metasurface structure with function of anomalous transmission is designed and fabricated. Full-wave simulation results prove that the plane electromagnetic wave normally incident from the bottom is nearly steered to 60 degrees by the designed Huygens metasurface at 10 GHz. The near-field measurement results are basically consistent with the simulations,which demonstrates the correctness of desinged metasurface further.
