Abstract: The expressions of the scattered field of a dielectric-covered conductor cylinder are derived by using the eigenfuction method. When the electric dimension of the cylinder is large and the thickness of the dielectric layer is small, a simple form of surface impedance of the cylinder is obtained. The distribution of total field and the total RCS per length are analyzed.

Key words: lossy material, scattering, surface impedance
