题目：Nanoscale Optics with Plasmonic Lattices报告人：Teri W. Odom时间：2023年8月24日 16:00地点：理学院郑裕彤大讲堂摘要：Optical metasurfaces are engineered planar structures with rationally designed building blocks that can manipulate light in new ways. However, less attention has been devoted to functionalization of the units or their integration with responsive materials. This talk will disc...
