Starting off with the basic rule of electrostatic field,the authors derive an expression for the electrostatic potntial of charged ellipsoid in anisotropic media by the method of equal effects.

Based on the ellipsoidal coordinates,we obtain the spacial distribution of electric potentials of a composits of a coated ellipsoid embedded in an infinite host via solving the Laplace equations and matching the boundary conditions.
