N2 - Advanced high-performance microwave absorber development now revolves around achieving better microwave absorption performance and intelligent electromagnetic property control. Effectively adjusting electromagnetic microwave dissipation qualities throughout a wide frequency range has been mostly unexplored, particularly for manufactured absorbers. Innovative and high-performance absorber materials are produced and analyzed in this study. Solvothermal preparation is used to synthesize polygonal-shaped CuCo2S4 particles that are embellished with Cu2S particles. The permittivity and permeability of polygonal CuCo2S4 particles decorated with Cu2S particles are significantly altered, which further affects the nanocomposite's performance in terms of microwave absorption. At a filler loading of 40 wt percent, the composite exhibits exceptional microwave absorption capabilities, and at a thin thickness of 1.5 mm, its effective absorption bandwidth (EAB) approaches 4.5 GHz, covering the whole X-band frequency range. The produced composite has outstanding dissipation qualities owing to the synergistic effects of numerous attenuation mechanisms and hetero-interfaces, where the ideal microwave dissipation strength is up to −32 dB.
