Abstract
We present a self-consistent quantum-mechanical formulation of the nonlocal dynamical potential near the surface of a solid describable in a coordinate system in which Laplace equation is separable. We apply the formulation to calculate image potential on surfaces with uniform curvature, i.e. planar, spherical and cylindrical surfaces. We also calculate the dielectric function ε(ω) and dispersion relations of surface modes in these systems.
