摘要：

The charge distribution and dipole moment in a system of interacting metallic nanowires in external electric field were found and used to calculate the plasmon energies governing optical properties of these nanostructures. The in-line alignment of nanowires caused a redshift of the plasmon peak while their parallel arrangement caused a blueshift. The dependence of these shifts on the separation between nanowires was calculated and compared with the recent experimental data on linear chains of Au nanorods.
