To overcome this constraint, an impedance matching\u2010guided multilayer engineering strategy is proposed to spatially decouple this trade\u2010off via electromagnetic gradient architectures enabling ultra\u2010broadband EMW absorption. To verify this strategy, magnetic Ni@MXene absorbents with tuneable electromagnetic ratios were synthesized via electrostatic self\u2010assembly and in situ reduction, followed by shear\u2010induced alignment to construct homogeneous laminated composites. While the single laminated composites deliver strong absorption (minimum reflection loss,\n                    <jats:italic>RL<\/jats:italic>\n                    <jats:sub>min<\/jats:sub>\n                    of \u221262.21\u00a0dB) yet limited effective absorption bandwidth (EAB, 3.68\u00a0GHz). By assembling the laminated composites into the electromagnetic gradient multi\u2010layered composite with optimized stacking sequence and layer thickness based on our impedance matching\u2010guided multilayer engineering, a three\u2010layer structure composite (G3) achieves an ultra\u2010broad EAB of 10.4\u00a0GHz and a\n                    <jats:italic>RL<\/jats:italic>\n                    <jats:sub>min<\/jats:sub>\n                    of \u221260.12\u00a0dB. This exceptional performance stems from synergistic impedance matching for wave penetration and cascade dissipation across the thickness direction. This work provides a design framework for broadband high\u2010efficiency EMW absorbing materials with implications for next generation of electromagnetic stealth technology.\n
