Abstract :
A new UTD solution is presented for describing the triple diffraction mechanism, when straight wedges in arbitrary configuration are illuminated by a source at finite distance. The proposed UTD coefficient permits to uniformly describe the field at any aspect, in particular including the case of overlapping transition regions. The analytical triple diffracted ray field expression is simple and provides a new effective engineering tool within a UTD framework, as required in a modern ray-based code.
