Ultra-broad-band electromagnetic absorption materials and structures are increasingly attractive for their critical role in competing with the advanced broad-band detection systems. Mechanically soft weak wax-based composites known to be insufficient serve practical applications. To break through such barriers, here we developed an innovative strategy enable robust repairable meta-structures by employing a three-dimensional (3D) printed polymeric patterned shell. Because of integrated merits from both dielectric loss mechanically 3D shells, as-fabricated bear mechanical collision compression, coupled ultra-broad-band (7-40 75-110 GHz, reflection smaller than -10 dB) approaching state-of-the-art materials. With assistance experiment simulation methods, design advantages mechanism shells substantially promoting performance have been demonstrated. Therefore, universal that could widely extended other categories highlights smart stage on which high-performance multifunction envisaged.
