“…On the other hand, the absorption mechanism of different systems materials, such as the electron polarization and interfacial polarization of carbon materials and the natural ferromagnetic resonance and domain wall resonance of ferrite materials, 30–32 will affect the broadband absorption of the metastructure, resulting in different electromagnetic field distribution and strong absorption positions. In addition, the morphology and mechanical strength of the composite will be affected by the composition of the composite, which will affect the mechanical bearing properties of the metastructure 33–37 . However, systematic and comprehensive analysis of the electromagnetic and mechanical properties of these typical absorbing metastructures is rarely studied.…”

Complex structural configuration design is necessary for dielectric‐magnetic lossy composites to achieved broadband microwave absorption in civil and defense applications. Based on the unique space filling characteristic of fractal structure, the honeycomb metastructure can possess microwave absorption and mechanical resistance. However, traditional molding technique was difficult to realize complex shape of metastructure. Herein, the dielectric‐magnetic filament with different concentration of carbonyl iron particles was fabricated by high‐temperature extrusion process. The multi‐physical honeycomb metastructure with gradient layers was printed by fused deposition modeling (FDM) in a large size. The printed dielectric‐magnetic samples exhibited strong dielectric‐magnetic loss with high printing quality. The honeycomb metastructure achieved broadband microwave absorption in the −10 dB bandwidth of 9.6–18 GHz with tensile strength of 31 MPa. The results indicate that FDM is useful to fabricate metastructure with complex shape for broadband microwave absorption. The dielectric‐magnetic properties of filament are magnified by metastructure design. The proposed design‐fabrication process is promising for functional structure realization with complex shape in the future.Highlights1. Magnetic filament was fabricated for functional 3D printing.2.
