Diffraction of an Electromagnetic Plane-wave by a Metallic Strip

The diffraction of an E-polarized and an H-polarized plane waveby an imperfectly conducting metallic strip on which are imposedimpedance boundary conditions is considered. The two independentproblems are solved by a method due to Jones based on the Wiener-Hopftechnique, and expressions for the extinction cross sectionare given in ascending powers of the reciprocal of the wavenumber.
