Figure 5. Correlation between reflection loss (RL) and the quarter-wavelength (λ/4) matching condition for (A) CIP, (B) CIP@C, and (C) CIP@C@LM. Normalized input impedance (Z) maps of (D) CIP, (E) CIP@C, and (F) CIP@C@LM; (G) Attenuation constant () of the three composites; (H) Performance benchmarking of representative CIP-based absorbers reported recently in terms of RLmin and EABmax. CIP: Carbonyl iron powder; LM: liquid metal; EABmax: maximum effective absorption bandwidth; RLmin: minimum reflection loss.
