The electromagnetic scattering from an impedance cylinder embedded in a nonconcentric dielectric cylinder is derived rigorously by using the boundary value technique. The two cylinders are assumed to be infinite in length and of circular cross section. The incident electromagnetic field is in terms of an electric or a magnetic field component parallel to both cylinder axes. The problem is two dimensional and the solution to either type of polarization (TM or TE) can be done independently. Plane wave and line source excitations are considered in this analysis. The effects of various geometrical and electrical parameters (such as frequency, cylinder radii, permittivity, surface impedance, and eccentricity) on the near-field distribution and the far-scattered-field pattern are examined. Bistatic and monostatic scattering cross sections of the composite cylinder are also investigated in order to minimize or maximize the radar cross section
