Smarter, faster design of metasurfaces that scatter radar waves
A hybrid genetic algorithm and a new “spiralling cross” unit cell yield an X-band coding metasurface with up to 21 dB radar cross-section reduction, validated by measurements.
A transparent graphene “smart mirror” for 6G terahertz links
A transparent, graphene-based reconfigurable intelligent surface steers THz beams for 6G, with a realistic design that accounts for losses and coupling between cells.
