摘要
We consider the accuracy improvement of the high frequency scattered fields from the 3-D convex scatter by the Fock current and the incremental length diffraction coefficient (ILDC) technique. We propose the numerical contour deformation method to calculate the Fock currents, and treat them in the scatterer's lit and shadow regions, separately. Then, by adopting the ILDC technique, high frequency scattered fields are clearly formulated in the lit, shadow and transition regions of the 3-D convex scatter, respectively. Compared to the PO scattered field from the 3-D convex sphere, numerical results demonstrate the significant accuracy enhancement of the scattered field via the Fock current approach.
