摘要：

Anew UTD solution is presented for the description of the ray triply diffracted by straight wedges in arbitrary configuration, illuminated by a spherical wavefront field. The proposed UTD coefficient permits to uniformly describe the field at any aspect, in particular including the case of overlapping transition regions, where the subsequent application of UTD single wedge diffraction coefficient fails. The triple diffracted ray field is expressed in an analytical form, providing physical insight into the triple diffraction mechanism, and a new effective engineering tool within the UTD framework, as required in a modern ray-based code.
