Abstract

In this paper, an FMM-accelerated and high-order accurate Nystorm's solver for analyzing wave propagation over large terrains with arbitrary profiles is implemented. The current implementation can be a valuable tool for validating existing asymptotic-based algorithms; in particular, it can be a convenient alternative for obtaining diffraction coefficient parameters, as is shown here for a canonical class of smooth dielectric surfaces.
利用二维高精度fmm加速Nyström求解器模拟地形传播和衍射
本文实现了一种fmm加速的高阶精度Nystorm求解器,用于分析任意剖面大地形上的波传播。当前的实现可以是验证现有的基于渐近的算法的有价值的工具;特别是,它可以作为一种方便的替代方法来获得衍射系数参数,如图所示的一类典型的光滑介电表面。
