Analysis of the reflection properties of rectangular elements printed on a dielectric slab

The spectral domain dyadic Green's function is developed for stratified media. Poisson summation formula is used to transform the infinite spectral integrals into infinite double summations for discrete frequencies and make it applicable to infinite arrays of conductors printed on a dielectric slab. A Galer kin method is used to descertize and solve the electric field integral equations for the geometry of a two dimensional array of rectangular patches.
