| description | <p>Double-layer structure absorbing materials based on the impedance matching principle and transmission line theory can effectively improve the electromagnetic wave absorbing properties. In this paper, the electro-magnetic wave absorbing properties of double-layer absorbers (2 mm thickness), where multiwall carbon nanotube (MWCNT)-La(NO<sub>3</sub>)<sub>3</sub>/polyvinyl chloride (PVC) and MWCNT-Fe<sub>3</sub>O<sub>4</sub>/PVC composites had been taken turns as the absorption layer and matching layer, were investigated in 2<sub> </sub>–<sub> </sub>18 GHz range. The absorbing properties of single- and double-layer structure and different each-layer thickness with two types of combinations were compared. The results showed that the design of double-layer structure for composites could effectively broaden the absorption frequency area, and increase the absorption intensity. When MWCNT-La(NO<sub>3</sub>)<sub>3</sub>/PVC composite were used as absorption layers with 0.6 mm thickness, the absorption bandwidth (< –<sub> </sub>15 dB or > 97 %) of double-layer composite was the widest, reaching a maximum of about 3.36 GHz, and the absorption peak value was also the lowest about –<sub> </sub>46.02 dB at 16.24 GHz.</p><p>DOI: <a href="http://dx.doi.org/10.5755/j01.ms.23.3.16279">http://dx.doi.org/10.5755/j01.ms.23.3.16279</a></p> |
