Microwave Absorption(#br)In article number 2107265, Xuefeng Zhang, and co‐workers synthesize core@shell structural high‐entropy‐alloy@graphite (HEA@C) nanocapsules through an in‐situ arc‐discharged plasma approach. By changing the combinations of various transition elements of HEA cores, the optimized impedance matching, and improved interfacial polarization can be constructed, achieving significant microwave absorption properties at the gigahertz level.
