摘　　要：利用多层快速多极子算法(MLFMA)计算任意形状二维电大尺寸导体加介质体目标的电磁散射,介质体为镶嵌在电大尺寸金属体上的有耗介质。首先建立金属一介质体的混合积分方程,用共轭梯度法计算散射场;在叠代过程中用MLFMA,大大降低了计算时间。数据结果表明本文方法的准确和高效。multilevel fast multipole algorithm is applied for solution of electromagnetic field scattered by two--di- mensional structures consisting of both conductors and inhomogeneous dielectrics of arbitrary cross section. After set up a hybrid surface--volume integral equation,CGM was used to solve it. MLFMA was used to accelerate this course. Some numerical results have been obtained,showing the feasibility of proposed method.
