Electrostatics of a Nanowire Including Nonlocal Effects

We develop a method for calculating transverse static polarizability (per unit length) of a bulk nanowire by taking in to account the temporal and spatial dispersion. To describe these phenomena, we developed analytical theory based on local random-phase approximation and plasmon pole approximation. Our theory is very general in the sense that it can be applied to any material which can be characterized by a bulk dielectric function of the form (). The theory is applied to calculate the transverse static polarizability of dielectric nanowire.
