An Equivalent Coupling Iterative Hybird Algorithm

When using the MOM-PO hybrid algorithm, it is essential to analyze the interaction between high frequency region and low frequency region. The traditional method calculated the coupling matrix, which would need more computational resources. In this paper, we develop a new efficient MoM-PO hybrid algorithm which corrects the voltage matrix in low frequency region and uses iterative method in high frequency region. This method considers the coupling influence as a kind of iterative algorithm. So compared with traditional algorithm, it can calculate radar cross section efficiently with the quite high accuracy.
