Scattering of E-polarized waves from conducting strips in the presence of a magnetically uniaxial half-space-a singular integral equation approach

A method based on the theory of singular integral equations (SIE) is presented for treating analytically scattering by perfectly conducting infinitely long strips in the presence of a magnetically uniaxial half-space. A uniform plane wave, polarized parallel to the strip axis, is incident from the isotropic region. As a prerequisite to this approach, the E-mode scalar Green´s function of the structure is developed. Use of the reciprocity theorem then leads to a SIE for the current density induced on the scatterer´s surface. The solution of the SIE is carried out in the case of a strip parallel or perpendicular to the interface, either located above or embedded in the anisotropic space. Numerical results for the induced current density and for the scattered far field in a variety of cases are presented in graphical form
