Asymptotic solutions for the scattered field by a coated conducting cylinder including the scattering phenomena inside of a coating medium are presented in this paper. We derive the geometrical optics (GO) series solution including a multiply reflected GO, which is applicable in the deep lit regions far away from the geometrical boundaries (GBs) produced by the incident wave on the coated cylinder from the tangent direction. Also derived is the extended uniform geometrical theory of diffraction (UTD) series solution including a multiply reflected surface diffracted ray, which is applicable in the transition regions near the GBs and the deep shadow regions far away from the GBs. The validity of the asymptotic solutions proposed here is confirmed by comparing with the exact solution.
