| Abstraksi | : | Induced current distributions on conducting bodies of arbitrary shape modelled by NURBS (Non Uniform Rational B-Splines) surfaces are obtained by using a Moment Method approach to solve an Electric Field Integral Equation (EFIE). The NURBS surfaces are expanded in terms of Bezier patches by applying the Cox-de Boor transformation algorithm. This transformation is justified because Bezier patches are numerically more stable than NURBS surfaces. New basis functions have been developed which extend over pairs of Bezier patches. These basis functions can be considered as a generalization of "rooftop" functions. The method is applied to obtain RCS values of several objects modelled with NURBS surfaces. Good agreement with results from other methods is observed. The method is efficient and versatile because it uses geometrical modelling tools that are quite powerful. |
