Optimized discretization of 1D radiating panels

The present work focuses on the discretization of a 1D radiating panel. Once the panel has been dimensioned, a non-uniform array can give a workable solution for its practical implementation. Since the most significant singular values of the radiation operator are linked to those supported on the equivalent panel by a radiation integral, a generalized quadrature rule has been exploited to rearrange the radiation integrals into summations for array implementation. The quadrature also allows to select a set of weights needed to compute the excitation coefficients of the array elements. The validity of the technique is investigated and evaluated numerically.
