Abstract
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.
