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

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 wavesFile in questo prodotto:
