In this paper, the scattering of a plane electromagnetic wave by an infinite elliptic dielectric cylinder, coating eccentrically a circular metallic or dielectric inner cylinder, is treated. The electromagnetic field is expressed in terms of both circular and elliptical-cylindrical wave functions, which are connected with one another by well-known expansion formulas. Translational addition theorems for circular cylindrical wave functions are also used. If the solution is specialized to small values of h = k2C/2, where k2 is the wavenumber of the elliptic dielectric cylinder and c its interfocal distance, semianalytical expressions of the form S(h) = S(0)[1 + gh2 + O(h4)] are obtained for the scattered field and the various scattering cross sections of this configuration. The coefficients g are independent of h. Both polarizations are considered for normal incidence. Graphical results for the scattering cross sections are given for various values of the parameters. © 1997 IEEE. (EN)
