摘要：

We propose an improved effective-medium theory to study the interaction of the electromagnetic field with carbon nanotubes; composites. The axial response of the tube is obtained by an approximate solution of the parallel polarization scattering by spheroidal-shape inclusions, which takes into account the first-order geometric resonances and intra/inter-band transitions. The proposed theory is in conformity with experimental results published elsewhere. Mathematical derivations are provided to demonstrate that aligned carbon nanotube composites can support negative-refraction wave propagation under certain conditions. The theory is employed to perform a statistical analysis of carbon nanotube composites using practical probability distributions.
