N2 - The dielectric function of an electron-gas nanotube superlattice is calculated within the linear response. The intertube Coulomb interactions play an important role on the excitation properties. The electronic excitations of the nanotube superlattice are the superposition of those of the individual nanotubes. However, the collective plasma oscillations of these two systems quite differ from each other. A nanotube superlattice exhibits two-dimensional characteristics and is highly anisotropic.
