摘要：
By using a series expression of effective dielectric function epsilon(eff), the optical properties of alpha aligned carbon nanotubes arranged in a square array are investigated. The frequency dependence of the effective dielectric function is studied for various ratios rho (ratio between internal and external radii of carbon nanotube) and x (ratio between the lattice constant and the external radii of carbon nanotube). The results are compared with previous work in this field. It shows that the present method is simple, efficient, and can describe the experimental data quite well.
