The electrostatic interaction between two parallel charged cylinders of arbitrary diameters a1 and a2 is studied by solving numerically the nonlinear Poisson- Boltzmann equation. A limit of particular interest is that of a charged cylinder interacting with a charged plane (a1 → ∞). The interaction free energy is calculated, as a function of the separation distance between the cylinders, for either fixed charge density or mixed (fixed charge, fixed potential) boundary conditions.
