Synthesis, Characterization, and Microwave Absorption Property of the SnO2 Nanowire/Paraffin Composites

In this article, SnO2 nanowires (NWs) have been prepared and their microwave absorption properties have been investigated in detail. Complex permittivity and permeability of the SnO2 NWs/paraffin composites have been measured in a frequency range of 0.1-18 GHz, and the measured results are compared with that calculated from effective medium theory. The value of maximum reflection loss for the composites with 20 vol.% SnO2 NWs is approximately -32.5 dB at 14 GHz with a thickness of 5.0 mm.
