摘要 给出一种带小参数ε_0的优化完美匹配层(PML)方法,求解时谐散射问题.结果表明,该方法使得散射问题优化PML方法的计算不依赖于PML的厚度δ,且优化的PML解指数收敛于原问题的解. The author proposed an optimal perfectly matched layer (PML) method with small parameter ε_0 for solving time-harmonic scattering problem. The results show that the proposed method makes the calculation of the scattering problem of optimal PML method do not depend on the thickness 8 of the PML, and the exponential convergence of the optimal PML is the solution of the original problem.
