TOKYO, July 3, 2023 — Toppan’s millimeter-band reflector allows users to control the reflection angle of radio waves in the 1-10 mm wavelength band used in 5G mobile communications. The device is a lightweight flexible sheet with metasurface structure that can reflect 5G millimeter-band radio waves in specific directions, enabling high-speed multi-connection communications in radio dead zones. The surface of the sheet can also be printed with woodgrain, marble, and other designs, allowing its use as wallpaper in offices, factory buildings, and other interior spaces.
