Generalized Quadrature Rules for the Discretization of 1D Radiating Panels

We address the problem of discretizing a 1D radiating panel by a nonuniform array, determining the element positions and their excitations. The positioning of the array elements is performed by exploiting an optimized quadrature rule of the radiation integral. The excitation coefficients needed to radiate the field of interest are determined by an approach based on the Singular Value Decomposition (SVD) of the discrete radiation operator. Numerical results show the effectiveness of the technique.
