An efficient stable moments-physics optics (MOM-PO) hybrid method is proposed to calculate the disturbed pattern of an antenna around an electrically large platform modeled with Non Uniform Rational B Spline (NURBS) surfaces. Modifying the impendence matrix is used to implement the interaction of the MOM region and PO region for avoiding the convergence issue. The stationary phase method (SPM) is used to calculate the integral of the induced current. Both grouping of MOM regions and interpolation of stationary points are used to accelerate the present approach. Results obtained by this method agree well with that from the traditional Triangle MOM-PO. Comparison of execution times of each method demonstrates that the present method is accurate enough and much more efficient.

Key words: non uniform rational B spline, method of moments-physics optics, stationary phase method, accelerating technology
