Electric potential of a point charge embedded in a three-layered dielectric system with infinite planar interfaces is determined. Using the technique of Hankel transform, the electric potentials in all domains are obtained in closed form. Nondimensionalization of the solution reduces the governing parameters into three scalars: a normalized charge location and two dielectric constant ratios. Numerical parametric study reveals interesting, coupled influences of these parameters on the distribution of electric potential. Due to the linear nature of the electrostatic problem, the solution here can be extended to similar multilayered dielectric systems with a distribution of charges.
