In this work, a strategy of entropy\u2010driven phase engineering was proposed to regulate the evolution of EM spectra of carbon confined alloy composites. With increasing alloy entropy, the phase structure evolves from a single FCC phase to an FCC+BCC dual\u2010phase structure, accompanied by lattice distortion and point defects. These entropy\u2010induced effects effectively enhance electron scattering, moderately suppress excessive electrical conductivity, and weaken the skin effect, thereby significantly improving impedance matching. Moreover, abundant dual\u2010phase interfaces and lattice defects generate strong interfacial polarization and dipole polarization, which further boost dielectric loss. Importantly, polarization\u2010dominant medium\u2010entropy FeCoNiCu@C has been obtained by balancing the contribution between dielectric loss and impedance matching, as well as polarization loss and conduction loss, which realizes a broad effective absorption bandwidth (EAB) of 5.8\u00a0GHz at 1.8\u00a0mm and a minimum reflection loss (\n                    <jats:italic>RL<\/jats:italic>\n                    ) of \u221242.19\u00a0dB at 3.85\u00a0mm. This work demonstrates that entropy\u2010driven phase engineering accompanied by lattice distortion and point defects provides an effective strategy to synergistically regulate the evolution of EM spectra, thus achieving high\u2010efficiency EM wave absorption performance.\n
