摘要
Within the framework of macroscopic continuum theory, we formulate the calculation of the electrostatic potential for a charge in the presence of an anisotropic diffuse interface. We present a systematic method for determining the analytical forms of dielectric profiles for which the Fourier-Bessel components of the electrostatic potential can be obtained analytically. We discuss in detail a smooth exponential profile which manifests long-range diffuseness. On the basis of exact and approximate calculations, the image potential for this model is obtained in the main region of interest for applications.
