Abstract
We derive the novel asymptotic solutions for the scattered field when a cylindrical wave is incident on a coated conducting cylinder with a thin lossy dielectric material. We show that the extended UTD (uniform geometrical theory of diffraction) solution and the modified UTD solution derived by retaining the second order term are uniformly applicable in the transition region near the shadow boundary and in the deep shadow region in which the conventional UTD shadow region solution produces the substantial errors. The validity of the asymptotic solutions proposed here is confirmed by comparing with the exact solution.
