Petros Farah, et al., "Ultrafast nonlinear response of gold gyroid three-dimensional metamaterials." Physical Review Applied 2, (4), 2014, 044002. We explore the nonlinear optical response of three-dimensional gyroidal metamaterials, which show greater than tenfold enhancements compared to all other metallic nanomaterials as well as bulk gold. A simple analytical model for this metamaterial response shows how the reflectivity spectrum scales with the metal fill fraction and the refractive index of the material that the metallic nanostructure is embedded in. The ultrafast response arising from
