The method of moments (MoM) procedure was combined with the complex source point (CSP) type Green's function to obtain faster solutions. Even though by this way, the cpu times are reduced drastically for large scatterers, the accuracy of this combination of MoM and CSP type Green's function is not better than the original MoM. On the other hand, here we performed a combination between Nystrom method and a special Green's function having a beam type radiation. Then it is expected to obtain more accurate data compare to MoM due to the convergent nature of Nystrom algorithm. It is also obtained the better running time performance than the original Nystrom method. Also this beam type of Green's function is derived from a general formulation of surface equivalence theorem and so the beam waist on the scatterer can be adjusted to a small value. The results are demonstrated on a single flat PEC strip and these statements are verified in the numerical results by comparing the RCS patterns. It is seen that the RCS patterns are very similar to original Nystrom case. Also the convergence of the results can be seen in the relative error plots for the total scattering cross section.
