本文研究了一种计算二维时谐电磁波散射的重叠解方法。该方法可用于计算可穿透各向异性非均匀散射体或不可穿透障碍物的散射波。主要的重点是使用有限元实现的方法。我们证明了离散化问题的唯一解的存在性，并得到了该格式的最优收敛速度，数值例子验证了这一点。
We investigate an overlapping solution technique to compute the scattering of time-harmonic electromagnetic waves in two dimensions. The technique can be used to compute waves scattered by penetrable anisotropic inhomogeneous scatterers or impenetrable obstacles. The major focus is on implementing the method using finite elements. We prove existence of a unique solution to the discretized problem and derive an optimal convergence rate for the scheme, which is verified by numerical examples.
