Optical metasurfaces have been analyzed in recent years as promising platforms for manipulating light at the subwavelength scale. The meta-atoms can provide enhanced light-matter interactions and novel resonant modes to control spectral response or directions of the transmitted/reflected light. In this special session, we explore recent progress related to metasurfaces involving the structural coloring effect and wavefront manipulation with metallic or dielectric meta-atoms. The session will cover interesting advances in the design and fabrication of high-performance metasurfaces, including numerical design, fabrication, characterization and potential applications.
