摘要

我们提出了一种扩展的三维(3D)水波隐身的海浪。注意到二维水(浅水)波问题与三维(深水)波问题的等价性，将基于变量交换的二维隐身方法推广到海洋中自由表面重力波。研究表明，流体密度应具有各向异性，以掩盖近海构造。数值计算得到了COMSOL Multiphysics软件的验证。

Cloaking of ocean waves with anisotropic fluid

We present an extension of 3 dimensional (3D) water wave cloaking for ocean waves. By noting the equivalence between the 2D water (shallow water) wave problem and the 3D (deep water) problem, a 2D cloaking method based on the variable exchange is extended to free surface gravity waves in the ocean. It is shown that fluid density should have anisotropy so as to cloak an offshore structure. Numerical computations are confirmed by COMSOL Multiphysics.
