[IEEE 2018 International Conference on Microwave and Millimeter Wave Technology (ICMMT) - Chengdu, China (2018.5.7-2018.5.11)] 2018 International Conference on Microwave and Millimeter Wave Technology (ICMMT) - A Reconfigurable Electromagnetic Metasurface with Bifunctional Illusions

摘要： A planar dynamically bifunctional metasurface is proposed to rebuild its scattering field as a convex or a concave mirror illusion. Generalized Snell’s law and phase compensation principle are used to analyze the proposed metasurface. A novel unit cell, with controlled reflection phase, is used to design the metasurface and transform electromagnetic illusion. The illusion performance of the presented metasurface is verified with simulation results. With the advantages of reconfigurability, low profile, and easy integration, the proposed metasurface can be widely used in the fields of electromagnetic metamaterials and scattering regulation.
