Ultrathin and Flexible Screen-Printed Metasurfaces for EMI Shielding Applications

An ultrathin, lightweight, and flexible metasurface for band-stop electromagnetic interference (EMI) shielding purpose has been designed and fabricated using screen-printing technology. Using a 1.8 GHz band-stop EMI shield as a design example, a prototype of a screen-printed metasurface has been validated using measured and numerically computed results. Hence, screen printing can be an attractive option for flexible and lightweight shields that can be easily applied on the walls and windows of a room to block specific wireless communication band so as to protect critical electronics instruments from possible EMI.
