In this paper, a numerical method for the scattering problem of multilayered dielectric bodies of revolution is introduced. Since the scatterer may be eccentrically layered, and since the rotation axis of each layer may be different from each other, conventional methods for bodies of revolution are not applicable to the scattering problem of this type. Thus, an iterative method is introduced in this paper. The electromagnetic problem of each layer is solved separately to take advantage of the rotational symmetry of each layer. This boundary value problem is solved from the outermost layer to the innermost layer, and this procedure is repeated until the desired degree of accuracy is obtained. The validity of this method is shown from numerical results. A mode-matching solution for a multilayered dielectric sphere is given to provide data which verify the accuracy of the method introduced in this paper
