Parallel body‐shaping of electrically large objects described by NURBS surfaces

Abstract: This article presents a systematic procedure to shape the body of an electrically large object in order to achieve a desired radiation/scattering pattern. In particular, the object surface is described by non-uniform rational B-splines (NURBS) and physical optics (PO) is used for electromagnetic field calculations. The NURBS control points and weights are considered as degrees of freedom for an evolutionary optimization algorithm. They are iteratively optimized according to the specific constraints of radiatio… Show more

“…The accuracy of curve point fitting and the representation of the interpolated points can be improved by considering least-square fitting [31,32], quadratic programming [33], and evolutionary algorithms [34] to change the weight vector parameters and optimize the curve. Ma and Kruth [31] used the least-square approximation for the fitting process of interpolation points and projected the three-dimensional (3D) data to the base plane for the calculation of the NURBS curve parameters.…”
