Abstract
In this work the scattering from an eccentrically coated infinite metallic cylinder is considered. The problem is solved using classical separation of variables techniques combined with translational addition theorems. For small eccentricities κd, where d is the distance between the two axes and κ the wave number of the dielectric coating, exact closed-form expressions of the form S(d)=S(0)[1+g′(κd)+g″(κd)2+O(κd)3] are obtained for the scattered field and the various scattering cross sections of the problem. Both polarizations are considered for normal incidence. Numerical and graphical results for various values of the parameters are also discussed.
