| Research Abstract |
Characteristic optical properties of carbon nanotubes were theoretically studied. A family effect for perpendicular polarization is weaker than that for parallel polarization. In calculations of depolarization effects, the Tamm-Dancoff type approximation can breaks down. A qualitative effect of a dielectric material around a carbon nanotube is dependent on whether the material is located inside or outside the nanotube. A numerical calculation method was developed for response of carbon nanotubes to an electric field caused by surface plasmon resonance in metal nanostructures.
