Skew incidence on a thick metal-dielectric join

A skew incidence solution is presented for the diffraction by a metal-dielectric junction. Some practical applications of this result relate to a characterization of surface propagation across the seashore and the scattering by airframe discontinuities including those found in conformal arrays. The two-dimensional version of this problem has been treated previously for E and H polarization, and it is shown that the new skew incidence solution reduces to these special cases when beta = pi /2. The generalized scattering matrix formulation and the Weiner-Hopf technique are used to solve the integral equations arising after enforcing field continuity across the dielectric interfaces and the condition that the tangential electric fields vanish on the metallic surfaces.<>
