AI总结:

本文提出一种自适应优化算法,用于设计具有指定性能的任意几何声学结构,通过自适应细化网格减少Tikhonov函数的值,实现对称声学材料的构造。

摘要:

我们考虑了构造具有指定性能的任意几何声学结构的问题。我们采用优化方法来解决这个问题,并在自适应细化的网格上最小化Tikhonov函数。这些网格仅在声学结构应设计的地方进行局部细化。我们的特殊对称网格细化策略结合插值过程,允许构造具有指定属性的对称声学材料。所提出的自适应优化算法的效率通过在二维中构造对称声学材料来示例说明。

英文摘要:

We consider the problem of the construction of the acoustic structure of arbitrary geometry with prescribed desired properties. We use optimization approach for the solution of this problem and minimize the Tikhonov functional on adaptively refined meshes. These meshes are refined locally only in places where the acoustic structure should be designed. Our special symmetric mesh refinement strategy together with interpolation procedure allows the construction of the symmetric acoustic material with prescribed properties. Efficiency of the presented adaptive optimization algorithm is illustrated on the construction of the symmetric acoustic material in two dimensions.
