The mixed boundary value problem associated with scattering of obliquely incident water waves by a flexible porous barrier of different barrier configurations is considered here. The originally defined half-plane problem is converted into a quarter-plane problem. Then a novel connection is established between the solution potential of the converted problem and a resolvable potential in the quarter-plane. Further Galerkin approximation is used to obtain close bounds for the reflection and the transmission coefficients. Numerical results are presented for scattering quantities against various parameters in each of the problems under consideration.

垂直弹性多孔屏障的斜水波散射

这里考虑了与斜入射水波被不同屏障配置的柔性多孔屏障散射相关的混合边界值问题。最初定义的半平面问题转换为四分之一平面问题。然后在转换问题的解势与四分之一平面中的可解势之间建立新的联系。进一步的伽辽金近似用于获得反射系数和透射系数的近界。在所考虑的每个问题中，针对各种参数给出了散射量的数值结果。
