应我校物理学院院长田浩教授邀请，英国赫瑞-瓦特大学Chen Xianzhong教授来校做平面光学技术用于波前工程方面的学术报告。欢迎感兴趣的老师和同学参加交流。
报告题目：Flat Optics for Wavefront Engineering
报告时间：2023年12月19日（星期二），下午14:00-15:00
报告地点：理学楼717
报告摘要：
Device miniaturization and system integration are two continuing trends. However, further reduction in the thickness of the optical elements is hindered by the design theory. Optical metasurfaces consisting of nanostructures can control light propagation in a desirable manner, providing new opportunities to develop ultrathin optical devices with unusual functionalities. In this talk, I am going to review the current progress in optical metasurfaces and talk our recent work in metasurface based ultrathin optical devices (e.g., metalenses, holograms, optical vortex beams, multifunctional devices, and 3D polarization manipulation) and their applications in imaging, displays, encryption, and detection.
