A novel frequency selective structure with steady pass-band and broadband absorption properties

Design, preparation and electromagnetic characteristics analysis of single, double and three-layer cross-shaped frequency selective fabrics

“…[14][15][16][17] The results show that different conductive units and interlayer arrangements can greatly affect the electromagnetic transmission characteristics, which may increase the resonance peak, reduce the bandwidth, or even reverse the characteristics. [18][19][20] Therefore, more diverse filtering products could be developed through reasonable multi-layer structure design. However, the reported multilayer structure is mostly processed into the form of a composite plate by laser engraving, chemical coating, vacuum coating, and so on, [21][22] rarely involving flexible textile materials, which could be easily fabricated into multilayer structures through weaving, knitting, braiding or other textile finishing methods.…”
