Lecture: Metasurfaces: Physics and Applications


Speaker: Prof. Lei Zhou, Fudan University

Time & Date: 9:00 April. 13, 2018

Venue: Room 301 in the School of Physics


Abstract:

Metasurfaces, ultrathin metamaterials composed by array of planar “meta-atoms” with  pre-designed electromagnetic (EM) properties, have attracted extensive  attention recently. In this talk, I will give an overview on the  development of metasurfaces focusing on the research works done in my own group. After briefly mentioning our early efforts on using  homogeneous metasurfaces to manipulate EM wave properties, I will then  describe our series of works on gradient metasurfaces, including making surface-plasmon couplers, constructing Pancharatnam-Berry metasurfaces with nearly 100% efficiencies in both reflection and transmission  geometries, and combining graphene and metasurfaces to achieve  wide-range phase modulations.
