Artificially Magnetically Programmed Metamaterial Films for Enhanced Ultra‐Wideband Electromagnetic Response
Abstract
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° of oblique incidence under the arch method test, covering all the S, X, and Ku bands. This work highlights the potential of magnetic‐field‐guided fabrication as a versatile route toward intelligent, high‐performance EM absorption films and provides a profound insight into the relationship between artificially engineered metamaterial structures and EM response, which opens up the way for intelligent manufacturing of high‐efficiency EM wave absorption films.
