Abstract :
A numerical solution of the scattering problem of a three-dimensional dielectric object above an impedance surface is sought. First, the dyadic Green´s function of the problem which is amenable of numerical calculation is derived using an integral transformation. Then, the integral equation for the polarization current is cast as a matrix equation by employing the method of moments. Numerical results are presented.<>
