论文摘要
在制定单色波散射的问题以及对helmholtz方程的溶液的数值模拟时，存在计算不便：计算是在有限散射区域的离散节点上进行的，而散射波的辐射条件的离散网格则是在散射波的辐射条件下进行的。克服这种不便会导致一种新型的边界条件：非局部边界条件（或第四种条件）。
In the formulation of the problem of scattering of monochromatic waves and the numerical simulation of the solution to the Helmholtz equation, there is a computational inconvenience: the calculation is performed on a finite grid of discretization nodes of the finite scattering region, while the radiation conditions for the scattered wave are formulated at the infinitely distant boundary. Overcoming this inconvenience leads to a new type of boundary condition: a nonlocal boundary condition (or condition of the 4th kind).
