The diffraction problem for a plane wave incident on two parallel half-pIanes is solved by ray theory, that is, by the uniform asymptotic theory of edge diffraction. Tbe solution is found to be in complete agreement with tbe rigorous high-frequency expansion of the exact solution as presented by Jones. All discrepancies previously observed by Jones are clarified.
