摘要:
我们考虑标量波方程在由有限个无限圆柱波导和有限区域组成的域中的数值解法。本文旨在提供一个统一框架下完美匹配层(PML)方法和Hardy空间无限元方法的新收敛性分析。我们处理衍射和共振问题。理论误差界与数值实验误差进行比较。
英文摘要:
We consider the numerical solution of scalar wave equations in domains which are the union of a bounded domain and a finite number of infinite cylindrical waveguides. The aim of this paper is to provide a new convergence analysis of both the Perfectly Matched Layer (PML) method and the Hardy space infinite element method in a unified framework. We treat both diffraction and resonance problems. The theoretical error bounds are compared with errors in numerical experiments.
