Radio frequency characteristics of Fe-filled carbon nanotube film

Abstract: The conduction noise suppression in radio frequency region using film type of the Fe-filled carbon nanotubes and its epoxy composite was evaluated on a coplanar waveguide. Fe in carbon nanotubes have shown α-Fe crystalline structure and had a coercivity of 650Oe. The magnitudes of the signal attenuation of Fe-filled carbon nanotubes on coplanar waveguide were shown in the range of about 10–18dB/cm at 20GHz (the stop-band frequency region). The power losses of these films exhibited 65–85% at 20GHz in the stop-band frequency. [Copyright &y& Elsevier]
