摘　　要：本文介绍基于多层快速多极子方法(MLFMA)分析框架下的高效处理新方法和相关研究成果,重点讨论用于厚介质层散射分析的电流磁流混合场积分方程(JMCFIE)、用于多薄层介质散射的多层薄介质层(TDS)边界条件方法及其应用等;最后介绍了所研发的P-UEST软件及其在隐身飞行目标散射特性计算中的应用成果。In this paper the efficient numerical methods for EM scattering from low observation targets have been introduced.These methods based on MLFMA and included some further improvements,among which the JMCFIE for surface integral equation of homogeneous dielectric scattering,the multi-TDS boundary conditions for volume integral equation of multi-layered dielectric scattering and their applications have been discussed in detail.Finally,the code,called as Parallelized Universal Electromagnetic Scattering Tool（P-UEST） and developed by our group for modeling of scattering from the stealth airplane,has been described.Some application examples have also been given in this paper.
