Optically transparent reflectarray articles and methods of making and using the same are provided. The reflectarray article includes a frequency selective surface (FSS) layer and a ground plane layer disposed on opposite sides of a dielectric substrate. The FSS layer includes a pattern of wire-like resonating metallic elements configured to reflect incident mmWaves, and the ground plane layer includes a pattern of metal-based conductor mesh to provide conductivity and high visible light transmittance.
