Query: Polarizability of nanowires at surfaces: Exact solution for general
  geometry   The polarizability of a nanostructure is an important parameter that
determines the optical properties. An exact semi-analytical solution of the
electrostatic polarizability of a general geometry consisting of two segments
forming a cylinder that can be arbitrarily buried in a substrate is derived
using bipolar coordinates, cosine-, and sine-transformations. Based on the
presented expressions, we analyze the polarizability of several metal nanowire
geometries that are important within plasmonics. Our results provide physical
insight into the interplay between the multiple resonances found in the
polarizability of metal nanowires at surfaces.
