Abstract :
A high-frequency solution for the scattering from thin dielectric screens is presented. It is heuristically derived by conveniently modifying the UTD solution for a perfectly conducting half-plane. The final dyadic expression satisfies reciprocity and to the first order, the boundary conditions on the faces of the dielectric screen. Numerical results are presented and compared with the exact solution for an impedance screen
