Abstract: 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.

Abstract: Articles to control an electromagnetic (EM) radiation in the range of 1 GHz to 100 GHz, and methods of making and using the same are provided. An EM controlling sheet structure includes a dielectric carrier layer and an array of metallic resonant elements supported by the dielectric carrier layer to form an EM metamaterial structure in a non-random pattern. The metallic resonant elements are oriented such that each metallic resonant element has an axis substantially parallel to each other and substantially parallel to a major plane of the dielectric carrier layer.

Abstract: Systems and methods using passive reflectors or reflectarrays are provided to enhance non-line-of-sight (NLOS) wireless signals. Multiple reflectarrays are combined and positioned to cover a wide range of user positions/beam angles. The passive reflectarrays include at least one of a first reflectarray configured to split an incident beam and a second reflectarray configured to steer the incident beam with an off-plane of incidence.
