An attenuation function expressed in terms of UTD coefficients for the multiple-wedge diffraction considering spherical-wave incidence

An attenuation function expressed in terms of UTD coefficients for the prediction of the multiple diffraction produced by an array of perfectly conducting wedges considering spherical-wave incidence is presented. The solution, validated with numerical results from the technical literature, sharply reduces the computing time over an existing formulation when the number of wedges is large. The result could be applied in the planning of microcellular mobile radio systems.
