摘要

将小波用于随机粗糙表面电磁波散射的数值模拟。由于小波的多分辨率分析、正交性、矩量消失等特性，矩量法得到了非常稀疏的阻抗矩阵。在新算法中，使用单点正交公式计算矩阵中的大多数项。该算法具有较高的效率和精度，为三维散射问题的数值处理提供了可行性。给出了二维散射问题的算例和比较。

Numerical study of random surface scattering using wavelets

Wavelets are used in the numerical simulation of scattering of electromagnetic waves from randomly rough surfaces. Owing to the multiresolution analysis, orthogonality, vanishing moment properties of the wavelets, very sparse impedance matrices in the method of moments (MoM) are obtained. In the new algorithm, the majority entries in the matrix are evaluated using a single-point quadrature formula. Because of the high efficiency and precision of the new algorithm, it is now feasible to handle 3D scattering problems numerically. Examples and comparisons are provided for 2D scattering problems.
