Experimental determination of microwave attenuation and electrical permittivity of double-walled carbon nanotubes
2006
Applied Physics Letters
Preserved Fulltext
The attenuation and the electrical permittivity of the double-walled carbon nanotubes (DWCNTs) were determined in the frequency range of 1-65 GHz. A micromachined coplanar waveguide transmission line supported on a Si membrane with a thickness of 1.4 µm was filled with a mixture of DWCNTs. The propagation constants were then determined from the S parameter measurements. The DWCNTs mixture behaves like a dielectric in the range of 1-65 GHz with moderate losses and an abrupt change of the
