The paper offers a procedure for the calculation of double and higher order diffraction at edges and right angle wedges, in the high frequency approximation. Such effects appear when double walled screens are erected along highways, and when waves are diffracted at the sides of buildings.

Zusammenfassung

In der Arbeit wird ein Verfahren zur Berechnung der Beugung zweiter und höherer Ordnung an Kanten und rechtwinkligen Keilen in der Näherung für hohe Frequenzen vorgestellt. Derartige Effekte treten auf, wenn doppelte Lärmschutzwände entlang von Autobahnen aufgestellt werden sowie bei der Beugung von Wellen an den Seiten von Gebäuden.

Sommaire

Cet article propose une procédure de calcul de diffraction par des dièdres et des coins à angle droit, à l'ordre deux et plus, dans l'approximation des hautes fréquences. De tels effets se produisent par exemple par interaction des ondes avec les écrans à double paroi que l'on érige le long des autoroutes, et avec les coins des immeubles.
