Nanowerk  November 27, 2024 Lightweight, low-cost metasurfaces and reflect arrays that are easy to stow and deploy are desirable for many terrestrial and space-based communications and sensing applications. A team of researchers in the US ( Columbia University, North Carolina State University, City University of New York) demonstrated a lightweight, flexible metasurface platform based on flat-knit textiles operating in the cm-wave spectral range. By using float-jacquard knitting to directly integrate an array of resonant metallic antennas into a textile, two textile reflect array devices, a metasurface lens (metalens), and a vortex-beam generator were realized. Operating as a receiving antenna, the […]
