Carbon nanotubes have excellent mechanical, electrical, thermal and magnetic properties, among the extraordinary properties of these materials can be traced to the absorption of electromagnetic waves. By placement of this materials in direction of electromagnetic waves, significant volumes of this waves have been absorbed and also it’s reduce the radar cross section from a finder view, in this study we have produced composite samples containing SWCNTs in the context of an epoxy resin based on standard dimensions for X-band with a multi-stage built method and then these samples have been analyzed by Vector Network Analyzer. Composite samples have been made in three weight percent, 1, 3 and 10. The result of this experiment shows the high amount of wave absorption for samples reinforced by carbon nanotubes. This amount of absorption greatly increase due to increasing of nanotubes weight percent, so that the average amount of absorption in the whole X-band for the mentioned percentages is 3.33712, 4.5889 and 12.6542 dB respectively. Also the amplified samples with 1, 3 and 10 weight percentages, showing increase in wave absorption about 22, 67 and 362 percent in comparison with pure resin. Finally samples have been evaluated with Micro Raman Spectroscopy and SEM images.
