Abstract
Uncovering the structural-functional relationship between metamaterial structure and the electromagnetic spectrum has always been a long-standing challenge with significant scientific and practical implications. Here, we report a magnetic field-assisted assembly strategy that enables large-scale programmable fabrication of metamaterial films with reconfigurable strip and web arrays. For the first time, the individual contribution and synergistic effect of array nodes or junctions on affecting the EM parameters and absorption ability are figured out with the help of assembly and regional disassembly of structural films. As a consequence, AW-2 films exhibit an effective absorption bandwidth of 7.32 GHz when 60°…
