Rheologically Engineered 3D‑Printed Highly Loaded Magneto‑Dielectric Absorbers for Device‑Level Electromagnetic Compatibility (IMAGE)
Caption
- A rheologically engineered approach enables the 3D printing of high-loading (~84.06 wt%) magneto-dielectric composite inks, with quantitative composition–rheology–printability relationships established.
- 3D-printed GC honeycomb (GCH) absorber achieves ultra-broadband absorption covering 18 GHz–4 THz, with reflection loss (RL) ≤ − 10 dB and RLmin of − 84.30 dB in the terahertz band.
- The monolithic integration of the GCH absorber with a terahertz reconfigurable intelligent surface delivers a 3.3 dBi increase in main lobe gain and ~58% reduction in specular reflection beamwidth.
