Abstract

Abstract

I will describe the effort of my research lab in investigating structural dispersion engineering of meta-atoms and creating passive metasurface-based flat optical devices using the meta-atoms. These include broadband achromatic flat lenses for full-color imaging and phase-amplitude metasurface holograms for creating defect-free holographic objects.
