讲座内容:

        Metasurfaces, the 2D variant of metamaterials, have been at the forefront of optics research in the past decade, due to the simplicity and flexibility of their design, and the impact of novel devices which can be realised. Primarily designed using plasmonic effects – fabricated from patterned metallic nanostructures – metasurfaces suffered from poor performance when carrying out the desired response. This is due to the low interaction of light when transmitted through metallic thin films, where the efficiency is typically limited to ~15% or less.

         Here, I will talk about my work carried out during the last 5 years at both the University of Birmingham (Prof. Shuang Zhang) and, more recently, at the University of Glasgow (Prof. David Cumming), on developing metasurfaces which exhibit very high performance utilising reflection or transmission operation.
