Algorithm for the Computation of the Generalized Fresnel Integral

Giorgio Carluccio, Federico Puggelli, Matteo Albani

Open publisher page 22 citations

Abstract

The generalized Fresnel Integral appears as a canonical function in the uniform ray field representation of several high-frequency diffraction mechanisms, such as double wedge or vertex diffraction. Here we propose an algorithm for its calculation which is valid both for real and imaginary arguments as required for treating the general case in the uniform geometrical theory of diffraction framework.
