%X The hybrid iterative Method of Moments and Physical-Optics method of moments(MoM-PO) is used to analyze radiation pattern of antenna around an electrically large platform modeled with Non-Uniform Rational B-Spline(NURBS) surfaces. The formula of scatter field based on NURBS surface is deduced. Stationary Phase Method(SPM) is applied to the integral of induced current on the rational Bezier surface. The process of obtaining stationary point is accelerated by interpolation technique. Results obtained by this method and by MoM-PO based on triangle facet model agree well while the former is more efficient in execution time.
