Description

This lecture covers the design and properties of narrow band Fano-resonant metasurfaces, focusing on the phase control and spectral range. It discusses the influence of different nanostructures on the reflected wave, the central resonance, and the bandwidth tuning. The lecture also explores the visible range constraints for coinage metals like silver and aluminum, emphasizing anomalous reflection efficiency and agreement with Snell's law. Additionally, it delves into color routing using Fano-resonant metasurfaces at specific wavelengths, showcasing the angle of reflection and intensity variations.
