Willis coupling in water waves

چکیده
Abstract For mechanical waves, Willis coupling means a cross-coupling between stress and velocity or momentum strain. In contrary to its realization in acoustic elastic whether exists water as another kind of wave, is still unknown. Here, we propose establish the concept waves horizontal at free surface acceleration potential vertical displacement flux. Thanks wave feature proposed metamaterial’s resonating conditions can be tuned by using shoaling effect. With proper three-dimensional design, have significant effects with resonance long-wavelength regime. Furthermore, adding loss metamaterial, asymmetric reflectance absorption achieved, which are useful for applications such seismic isolation, coastal protection, water-wave energy-harnessing, also constructing non-Hermitian exceptional points.

متن کاملShallow Water Waves and Solitary Waves
Glossary Deep water A surface wave is said to be in deep water if its wavelength is much shorter than the local water depth. Internal wave A internal wave travels within the interior of a fluid. The maximum velocity and maximum amplitude occur within the fluid or at an internal boundary (interface). Internal waves depend on the density-stratification of the fluid. Shallow water A surface wave i...
متن کاملWater waves and integrability.
Euler's equations describe the motion of inviscid fluid. In the case of shallow water, when a perturbative asymptotic expansion of Euler's equations is considered (to a certain order of smallness of the scale parameters), relations to certain integrable equations emerge. Some recent results concerning the use of integrable equation in modelling the motion of shallow water waves are reviewed in ...
