High frequency diffraction of an electromagnetic plane wave by an imperfectly conducting rectangular cylinder

We shall consider the the problem of determining the scattered far wave field produced when a plane E-polarized wave is incident on an imperfectly conducting rectangular cylinder. By using the the uniform asymptotic solution for the problem of the diffraction of a plane wave by a right-angled impedance wedge, in conjunction with Keller´s method, the a high frequency far field solution to the problem is given.
