Title: High-efficiency, multifunctional, and tunable metasurfaces



Metasurfaces are ultra-thin metamaterials composed by artificial planar meta-atoms arranged in some specific macroscopic orders, which exhibit extraordinary capabilities to control electromagnetic (EM) waves. In this talk, I briefly summarize our latest experimental results on employing metasurfaces to control electromagnetic waves. Specifically, I will show how to realize a photonic spin-Hall effect with nearly 100% efficiency in both reflection and transmission geometries [1], how to achieve surface-plasmon couplers that can excite surface plasmon polaritons very efficiently [2], and how to actively control EM waves in THz [3] and GHz regimes [4], based on a compete phase diagram for metal/insulator/metal metasurface [5]. Finally, if time permits, I will introduce our latest efforts on constructing high-efficiency multifunctional metasurfaces under different configurations (purely reflection and transmission geometries and even in the full space) exhibiting diversified functionalities [6].

Lei Zhou, Joined Physics Department of Fudan University in 2004 as a professor, and became a “Xi-De" Chair Professor since 2013. Starting from 1993, he has been working in the fields of magnetism, meta-materials, photonic crystals and plasmonics, and he has published over 140 papers in scientific journals including Nature Materials, Phys. Rev. X, Phys. Rev. Lett., Light-Sci. Appl., Nano Lett. He is the co-author of a monograph (Springer) and 3 book chapters. He has successfully held several international conferences as general chair, severed as program committee members or session chairs in many top international conferences, and has been invited to give invited talks in many top international conferences. Professor Lei Zhou got many awards, including the NSFC "Grant for Outstanding Young Scientist" (2007), the "Chang Jiang Scholars Program" Chair Professorship (2009), the “OSA Young Scientist Award” (2016) and the “APS Outstanding Referee” (2017).
