Metasurface Glass for Wireless Communication and Energy Saving

Abstract

With the growing global energy demand and environmental issues, energy saving technologies are becoming increasingly important in the building sector. Conventional windows lack energy saving and thermal insulation capabilities, while Low emissivity glass (Low‐e glass) attenuates mobile communication signals while reflecting infrared. Therefore, this paper aims to design a type of windows for the “Sub 6GHz” frequency band of 5G. These windows combine the inherent transparency of traditional glass windows with the energy saving properties of Low‐e glass, while also ensuring optimal communication performance within the 5G (Sub 6G) band. The metasurface glass is fabricated and subjected to simulation‐guided experiments to evaluate their reliability and practicality. The metasurface glass is rigorously assessed in terms of microwave transmission performance, infrared low emissivity performance, and energy saving and thermal insulation capabilities.
