Abstract
Results are presented of propagation experiments conducted to verify the accuracy of a novel ray-optical scattering model for engineered electromagnetic surfaces, a class of passive metasurfaces designed to enhance wireless signal coverage. The measurements were performed at 28 GHz, using a wideband channel sounder equipped with phased-array antennas. Measured results were compared to simulations performed with a commercial ray-tracing software tool incorporating the scattering model, showing excellent agreement for a 30°–60° diffuser deployed in a large office space.
