The new metasurface lens is made with an artificially engineered material featuring a large number of sub-wavelength unit cells arranged periodically on a two-dimensional surface. Elements arranged in various shapes on the metasurface substrate can be attached to a glass window to direct radio signals to specific points (“focal points”) indoors. It is believed that radio waves from an outdoor base station could be received on a window’s broad surface and then efficiently propagated to specific focal points inside a building with the help of repeaters and reflectors.
In addition, DOCOMO and AGC verified that structural design technology can be deployed to enable metasurface lenses to allow high-frequency radio signals to penetrate glass that has been coated for heat insulation.
The prototype metasurface lens will be presented during DOCOMO Open House 2021, which will take place online this February 4 to 7.
