摘　　要：针对传统电磁求解器存在计算速度慢、内存消耗大的难题,提出了一种基于自适应矩估计(adaptive moment estimation,Adam)的矩阵方程快速求解方法,用于提升矩量法的仿真效率,并结合相位提取基函数实现对电大目标的快速电磁仿真。数值算例表明:Adam能够实现矩阵方程的准确求解,且计算效率可得到较大提升。The traditional electromagnetic solver has the problems of slow calculation speed and large memory consumption.The adaptive moment estimate(Adam)is proposed to improve the simulation efficiency of method of moment(MoM).By combining the phase extraction(PE)basis function,the electromagnetic simulation of the electrically large target is realized.Numerical examples show that Adam can give the accurate result and improve the efficiency.
