Japanese telecom operator NTT DoCoMo collaborated with Metawave to demonstrate a 5G mobile communication system using 28 GHz, in what it claims is the world’s first demo of meta-structure reflect-array technology.
NTT DoCoMo described meta-structures as an artificial medium with optical characteristics developed by arranging structures that are sufficiently small with respect to wavelength, in the form of an array. The meta-structures reflector developed by Metawave uses very small structures, compared to the free-space wavelength, that are arranged across the array to have different shapes based on their position within the array.
