Ultra-light h-BCN architectures derived from new organic monomers with tunable electromagnetic wave absorption

Reduced graphene oxide decorated with octahedral NiS2/NiS nanocrystals: facile synthesis and tunable high frequency attenuation

“…This could be attributed to the improved impedance matching. 43 According to the fundamental mechanism of electromagnetic wave absorption, highly efficient microwave absorbing materials require not only good electromagnetic wave dissipation capability but also impedance matching. 44 Ideal impedance matching should satisfy |Z in /Z 0 | ¼ 1.0, which implies the complete entrance of incident EM wave into an absorber with zero reection at the air-absorber interface.…”

P-doped BN nanosheets decorated graphene as the functional interlayer for Li–S batteries

“…The high-resolution B 1 s spectrum can be fitted into three peaks, centered at 190.5, 191. [30] . Fig.…”

“…The obtained product was calcined under nitrogen flow at 850 °C for 6 h with a heating rate of 2 °C min −1 . Finally, BN-P nanosheets were obtained after the furnace was cooled naturally [30] .…”

Flexible Fe3Si/SiC ultrathin hybrid fiber mats with designable microwave absorption performance

“…Based on the back-panel model and l/4 cancellation theory, the maximum RL values would be realized when the phase difference between incident and re-ected wave at the air-absorber (AA) interface is 180 . [51][52][53] Besides, the amplitudes of the two waves that related to 3 r and m r have to be equal in order to achieve the optimal cancellation scenario. If the characteristic impedance matches well, more microwave would enter the absorbers and be dissipated.…”
