Scattering of E and H polarized waves from covered cylindrical structures

A modification of the method of discrete sources (MMDS) is applied for solving 2D scattering problems by metal (or dielectric) cylindrical structure covered with a dielectric layer. The scattering of E (or H) polarized incident plane and cylindrical wave was considered. The problems of accuracy, choosing auxiliary contours and impedance approximation in scattering problem are discussed.
