Experimental results indicate that Co/NC@void@C-700@MoS2 exhibited best absorption performance effective bandwidth 7.54 GHz (at 2.05 mm) minimum reflection −60.88 dB 1.85 mm). Furthermore, radar cross-section simulation demonstrate effectively suppresses scattering transmission EMWs perfect electric conductor substrates, implying its superior practical application value.
