本文提出了一种新的谐振区目标散射的计算方法──部件耦合分解法。这种方法在采用回路线栅模型的基础上，利用谐振区目标散射体中各部件散射体特性阻抗矩阵延续不变性的特点，考虑各部件散射体之间的相互电磁耦合作用，并应用数学上分块矩阵理论，以简化谐振区目标散射体的求解，利用这种方法，采用并行处理，可加快谐振区目标散射体的求解速度，扩大可求解问题的电尺寸，数值结果表明了本文提出的部件耦合分解方法的有效性。
In this paper, a new method to calculate the target scattering in the resonant region is proposed - component coupled decomposition. In this method, based on the loop wire grid model, by utilizing the characteristic of continuum invariance of the characteristic impedance matrix of the scatterers in the scatterers of the target scatterers in the resonance region, the mutual electromagnetic coupling between the scatterers of each component is considered, The block matrix theory is used to simplify the solution of the target scatterers in the resonance region. By using this method, the parallel processing can speed up the solution of the target scatterers in the resonance region and enlarge the size of the problem that can be solved. Numerical results show that The Efficiency of Component Coupling Decomposition Method.
