重新考虑了海冰边界上海浪的反射和透射。海冰被模拟为一个连续的，均匀厚度的薄弹性板，漂浮在任意恒定深度的水面上。与早期的解决方案不同，自由表面域和冰覆盖域之间的电位匹配是在所有深度进行的;以前的解决方案是不完全匹配的，因为每个域中的电位都是不足的。在本解决方案中，在解决方案中包括了迄今为止被忽略的无穷多个消逝模式，并且允许通过最小化从表面到海底的积分误差项来进行匹配。反射和传输被发现显着影响列入这些模式，这表明结论的基础上不完整的潜力可能是错误的。
The reflection and transmission of ocean waves at a sea ice boundary is reconsidered. The sea ice is modelled as a continuous, thin elastic plate of uniform thickness, floating on water of arbitrary constant depth. Unlike earlier solutions, matching of potentials between the free surface domain and the ice-covered domain is done at all depths; previous solutions were incompletely matched, as the potentials in each domain were deficient. In the present solution a number of the infinity of evanescent modes, which were hitherto ignored, are included in the solution and allow matching to be carried out by minimization of an integrated error term from surface to seafloor. Reflection and transmission are found to be markedly influenced by the inclusion of these modes, suggesting that conclusions based on the incomplete potentials may be substantially in error.
