“…To investigate the EMW absorption properties of the NiS 2 @rGO/PPy composite with different doping ratios, the measured complex permittivity and permeability were used to calculate the reflection loss values of the as-prepared composites by the following equation [43]:Zin=Z0tanhμrεr[μrεr(2πfdc)j] RL=20log|ZinZ0Zin+Z0| where Z in is the input characteristic impedance, Z 0 ≈ 378 Ω is the free space of impedance matching, ƒ is the frequency of EMW, c is the velocity of light in a vacuum, d is the thickness of the composites, and ε r and μ r are the complex permittivity and permeability, respectively. When the reflection loss value is lower than −10, −20 and −30 dB, more than 90%, 99%, and 99.9% of the EM energy is absorbed, respectively [44].…”

“…Various structures, such as nanowires, cubes, core–shell, yolk–shell, etc., have been applied to improve electromagnetic characteristics for high MA performance. Among all the reported structures related to MA, the yolk–shell structure exhibits considerable potential and competitiveness due to multiscattering dissipations, complementary ability, and interfacial polarization.…”
