✦ Synopsis

In this paper, the problem of diffraction of time harmonic, electromagnetic waves by a thin ideally conducting disk lying at the plane interface of two different media is considered. In this analysis, the incident w a r e is a plane w a r e travelling in a direction perpendicular to the plane interface of the two media. A Hertz vector formulation is applied to reduce our electromagnetie diffraction problem to a system of two scalar problems which are solved by the kelp of two pairs of Fredholm integral equations of the second kind. Low frequeney approximations to the tangential components of the magnetic intensity associated with the diffracted field at the surfaces of the disk, the induced surface eurrent density on the disk and the scattering cross section are obtained.
