Abstract
The canonical problem of evaluating the field scattered at a finite distance from the edge of an impedance wedge which is illuminated by a line source is analyzed. Emphasis is placed on an analysis of surface wave excitation mechanisms. In particular, high-frequency expressions for the coupled surface wave-space wave contributions are presented. Also, suitable high-frequency diffracted field contributions are obtained to provide the continuity of the total field at the shadow boundaries of the surface waves.<>Keywords
