Abstract

The electromagnetic wave shielding properties of the carbon coils with polyurethane composites were investigated in the frequency range of 0.25 ~ 1.5 GHz. The shielding effectiveness of the composite having the various-shaped carbon coils were measured and discussed according to the weight percent of the carbon coils in the composites with the thickness of the composites layers. We confirmed that the absorption was the main mechanism to shield the electromagnetic wave interference in the carbon coils composites.
