Abstract : The phase and first erm of the asymptotic re flected, transmitted, and incident fields at a conical interface are determined. The source is an electric dipole located upon and directed along the axis of the cone. Standard asymptotic methods are developed for the dipole in free space when the second medium has a real wave number. The results show how the cone angle and curvature modify the terms of the half problem, which has been solved previously. When the second medium has a smaller wave number than free space, the diffracted field that arises because of total reflection is also de termined. The results are incorporated in a table. Finally, the results are extended to a second medium consisting of a plasma. The model includes collisions but ion motion is neglected. The phase and amplitude become com plex, representing the analytic continuation of the theory applicable to real wave numbers. (Author)
