摘要

提出了用有限平坦阻抗带状光栅对声波散射进行分析的方法。相关的二维边值问题以全波方式考虑，并转化为一组耦合积分方程。在此基础上，我们建立了几个数学模型。研究的重点是具有显式渐近解的窄阻抗条光栅对声平面波的散射。

Mathematical Models of Acoustic Wave Scattering by a Finite Flat Impedance Strip Grating

Analysis of acoustic wave scattering by a finite flat impedance strip grating is presented. The associated two-dimensional (2-D) boundary-value problem is considered in the full-wave manner and cast to a set of coupled integral equations. Based on them, we build several mathematical models. The focus of research is on the acoustic plane wave scattering by a grating of narrow impedance strips that has explicit asymptotic solution.
