報告摘要: The dynamic interplay between metamaterials and plasmonics has enabled many innovative concepts. Despite their continuous blending, there are still several sub-fields not fully explored and limitations not yet resolved. For instance, metals do not support pronounced plasmonic resonances in the mid-/far-infrared regime; most metamaterials and plasmonic devices have fixed functionalities once fabricated. Since their optical properties rely on both the constituents and how the building blocks are shaped and organized, introducing variables, such as changeable material properties and/or reconfigurable structures, may lead to new opportunities for dynamically tunable metamaterials and plasmonics. In this talk, several possible solutions will be discussed. I will show plasmonic core/shell particles and their self-assembled clusters as infrared resonators, ultra-compact nanoantennas with switchable and unidirectional radiation properties, and tunable graphene metasurfaces for infrared light beam shaping. If time permits, I will also discuss another topic on nano optics beyond visible, namely the chiroptical sensing at ultraviolet wavelengths.

陈诉人简介: 姚侃博士分别于20067月、20097月在中國科學技術大學和中國科學院電子學研究所獲得工學學士、碩士學位,隨後在上海微系統所作爲研究助理事情兩年。20178月在美國東北大學電子工程系獲得博士學位後参加德州大學奧斯汀分校以博士後身份繼續從事研究。目前的研究興趣主要是微納光子學的理論及應用。
