Abstract
An improved hybrid method of moments and physical-optics (MOM-PO) method is presented to analyse an antenna around an electrically large platform modelled with non-uniform rational B-spline (NURBS) surfaces. A Ludwig integral combined with stationary phase method is used to calculate the integral of induced currents for overcoming the limitations of the existing NURBS MOM-PO method. Grouping of the MOM region is utilised to enhance computational efficiency. Comparison of the results obtained from this method with that from MOM and existing NURBS MOM-PO shows that the present method is feasible.
