Abstract :
The exact solution for scattering by a semi-infinite parallel-plane waveguide is expanded asymptotically for large separation distances between the two half-planes. The result yields a term-by-term comparison with the corresponding result derived by means of ray theory. The simple ray method does not yield complete agreement with the asymptotic form of the exact solution.
