本文提出了一种非常有效的求解多物体线性水波散射的方法。几个机构组装在模块中，这些模块被分组在周期性的无限线阵列中。然后，使用迭代方法，将这些无限阵列中的有限个堆叠在一起。计算由无限线阵列的模块的身体的散射的方法是代数精确的，而远场（或宽间距）的近似是用于计算的散射的一个有限的堆栈阵列。布洛赫传输通过双周期安排的机构进行了讨论，所以平均技术来抑制现象的情况下，或多或少随机分布的机构的线阵列的周期性假设。虽然该方法是通用的，可以在各种情况下使用，该方法的主要应用是计算在边缘冰区发生的浮冰的巨大领域的散射。前...
A very efficient solution method to the determination of the linear water-wave scattering by a large number of bodies is presented. Several bodies are assembled in modules, which are grouped in periodic infinite line arrays. Then, using an iterative method, a finite number of these infinite arrays are stacked together. The method to calculate the scattering by the infinite line array of modules of bodies is algebraically exact, while a far-field (or wide-spacing) approximation is used in the calculation of the scattering of a finite stack of arrays. Bloch transmission through doubly periodic arrangements of bodies is discussed, and so are averaging techniques to suppress phenomena introduced by the periodicity assumption on the line arrays for the case of more or less randomly distributed bodies. While the method is general and can be used in a variety of situations, the principal application of the method is to calculate the scattering by vast fields of ice floes which occur in the Marginal Ice Zone.
