Enhancing the accuracy of hybrid SBR/MoM method based on new interaction

A new accurate hybrid SBR/MoM method is presented in this paper. It considers the interaction in MoM region by calculating the near scattered field instead of the conventional multi-bounce field from SBR region. By applying the SBR method, the near scattered field from SBR region impact on the MoM region is calculated and it finally contributes to the modified excitation vector in MoM matrix equation. Representative numerical results are given to demonstrate the effectiveness and high accuracy of the proposed method.
