一类多重障碍散射问题的数值算法

摘要

We proposed a new numerical algorithm for scattering problem of multiple obstacles.The algorithm used the linear combination of single layer potential function and double layer potential function to approximate the scattering field,without need to truncate and partition the domain,and the application process was simple and the convergence rate was fast.Numerical examples show the algorithm is effective.%针对多个散射体的障碍散射问题提出一种新的数值算法.该算法利用单层位势函数和双层位势函数的线性组合近似散射场的性态,无需截断与剖分区域,应用过程简单,收敛速度快.数值算例表明了算法的有效性.
