Abstract : Four coupled Fredholm integral equations of the second kind are derived for the electric and magnetic fields interior and exterior to a smooth, bounded, closed, three dimensional scatterer of permittivity, permeability, and non-zero finite conductivity, when the scatterer is illuminated by a time harmonic, monochromatic, otherwise arbitrary field. The surrounding medium has the properties of vacuum. The kernels of these equations are dyadics constructed from potential functions associated with the scattering surface. If the frequency of the incident field is sufficiently small, the integral equations may be solved in a standard Neumann series. (Author)
