Construction of core-shell structured SiO2@MoS2 nanospheres for broadband electromagnetic wave absorption

Synthesis of nitrogen-doped graphene aerogels modified by magnetic Fe3O4/Fe/C frameworks as excellent dual-band electromagnetic absorbers

“…Generally speaking, when designing advanced EMW absorbers, two important parameters of impedance matching and attenuation loss must be considered. 48–50 The attenuation constant ( α ) is commonly used to evaluate the EMW dissipation ability, which can be expressed as follows: 48–50 …”

“…The modulus of normalized input impedance (| Z in / Z 0 |) is widely utilized to assess the impedance matching condition, which can be calculated using the following equation: 48,49 …”

Magnetic Multilayer Composites Based on Carbon Nanotubes Modified SiC/BaFe12O19 for Wideband Microwave Absorption

“…It can be seen from Figure d,e that the real part of the permeability shows an upward trend, while the virtual part of the permeability shows a slight downward trend. When the operating frequency is higher than 0.1 GHz, the magnetic loss mainly comes from eddy current loss and natural ferromagnetic resonance, among which the natural ferromagnetic resonance is related to the contribution of shape anisotropic. , The comparison of absorbing properties of S1–S4 with different EM parameters is given in Figure S2 (Supporting Information). As can be seen with the increase of EM parameters, the composite exhibits a higher absorption strength.…”

Recent Progress and Outlook on the Emerging Low-Dimensional MoS2 Nanostructures for Microwave Absorption

“…SiO 2 @MoS 2 core–shell architecture nanospheres were constructed, in which MoS 2 nanosheets were irregularly growing on SiO 2 . The prepared SiO 2 @MoS 2 nanospheres achieved a maximum RL of −49.3 dB and EAB of 7.4 GHz at 3.2 mm …”
