The exact solution efficiency of large-size three-dimensional electromagnetic modeling of complex objects was im-proved. The improved mode of MLSSM (multilayer simple sparse matrix algorithm) based on ACA (adaptive crossover algo-rithm)was adopted. By the theory and realization process analysis,the algorithm was verified in the experiment. The experimen-tal results show that the improved ACA algorithm can improve computational efficiency more significantly than point-by-point computation of the moment method,the memory requirements of improved MLSSM is reduced by about half,and the matrix structure is improved significantly. The speed of iterative solution process is greatly increased. The comparative results indicate that the MLSSM has the advantages of reducing computational complexity and analyzing large complex objects in semi-space. The study has certain significance in theory and application for the optimization of electromagnetic modeling of complex objects.
